Sodium silicate has been used to control lead levels in drinking water, but there is little theoretical support for this practice. We find that sodium silicate is not effective in controlling lead release from lead(ii) carbonate.

Resumo:

AbstractThe lead silicate minerals from Franklin, New Jersey, occurred in two separate assemblages. One of these is characterized by esperite associated with hardystonite and occasional larsenite. The second assemblage can be considered as two parts: one consists of margarosanite, barysilite, nasonite, and ganomalite; the other contains roeblingite and hancockite, together with a number of highly hydrated phases. Chemical analyses indicate that these species conform to their theoretical compositions. There are no simple lead silicates at Franklin; all are compound silicates of Pb with Mn, Zn, and Ca.

In the present work, lead silicate glasses have been prepared withdifferent amount of lead oxide content. Structure properties such asX-ray diffraction, AFM, and FTIR analyses have been done. Theexceeding of PbO content more than 25wt% revealed a decreasing indensity. The X- ray revealed that the strongest peak related toHexagonal silica dioxide and the other crystal phases formed wererelated to silica oxide (SiO2) and lead oxide (PbO). Growth anddecayed phases in X-ray have been observed with changing leadoxide content. Homogeneous surface was obtained using AFManalyzer with an average diameter around 100 nm. Infrared spectrumis characterized by the presence of large absorption band between1200 and 900cm-1 and have its maximum at 1080 cm-1 which istypical to stretching vibrations of Si–O–Si bonds, another bandsnoticed were attributed to Pb–O–Pb, Pb–O–Si, [AlO4]-tetrahedron,and to Si–O–Al bond.

Resumo:

This study compared sodium silicate and zinc orthophosphate for their ability to decrease lead and copper release from pilot-scale premise plumbing in low alkalinity (<5 mg/L CaCO3) water. The study used pipe loops (to age the water) connected to copper pipe rigs. The copper pipe rigs were constructed using 50:50 lead:tin solder, which provided the only source of lead. Three different treatments were compared, using the same source water: phosphate (0.8 mg-PO4/L at pH 7.3), sodium silicate with pH control (18 mg-Si/L at pH 7.3), and sodium silicate (18 mg-Si/L at pH 6.3). Lead and copper levels (both total and dissolved) were measured following the copper pipe rig after two different stagnation times (24 h, 30 min). The phosphate treatment consistently resulted in significantly lower lead release compared to sodium silicate at the same pH of 7.3. The phosphate treated pipe rigs released 12 μg/L and 2 μg/L lead following the 24 h and 30 min stagnation times, respectively. The sodium silicate with pH control system released 46 μg/L and 6.7 μg/L lead following 24 h and 30 min stagnation time, respectively. The sodium silicate treated pipe rigs released 27.4 and 4.6 μg/L lead following the 24 h and 30 min stagnation time, respectively. The phosphate treatment also consistently released less copper than both the sodium silicate with pH control treatment and the sodium silicate treatment. However, more lead particles were observed in the phosphate treatment compared to either of the sodium silicate treatments. The difference in performance between the sodium silicate corrosion inhibitor at two different pH levels, suggests that the performance of sodium silicate could be further optimized.

Resumo:

AbstractThe structure hierarchy hypothesis states that structures may be ordered hierarchically according to the polymerisation of coordination polyhedra of higher bond-valence. A hierarchical structural classification is developed for sheet-silicate minerals based on the connectedness of the two-dimensional polymerisations of (TO4) tetrahedra, where T = Si4+ plus As5+, Al3+, Fe3+, B3+, Be2+, Zn2+ and Mg2+. Two-dimensional nets and oikodoméic operations are used to generate the silicate (sensu lato) structural units of single-layer, double-layer and higher-layer sheet-silicate minerals, and the interstitial complexes (cation identity, coordination number and ligancy, and the types and amounts of interstitial (H2O) groups) are recorded. Key aspects of the silicate structural unit include: (1) the type of plane net on which the sheet (or parent sheet) is based; (2) the u (up) and d (down) directions of the constituent tetrahedra relative to the plane of the sheet; (3) the planar or folded nature of the sheet; (4) the layer multiplicity of the sheet (single, double or higher); and (5) the details of the oikodoméic operations for multiple-layer sheets. Simple 3-connected plane nets (such as 63, 4.82 and 4.6.12) have the stoichiometry (T2O5)n (Si:O = 1:2.5) and are the basis of most of the common rock-forming sheet-silicate minerals as well as many less-common species. Oikodoméic operations, e.g. insertion of 2- or 4-connected vertices into 3-connected plane nets, formation of double-layer sheet-structures by (topological) reflection or rotation operations, affect the connectedness of the resulting sheets and lead to both positive and negative deviations from Si:O = 1:2.5 stoichiometry. Following description of the structural units in all sheet-silicate minerals, the minerals are arranged into decreasing Si:O ratio from 3.0 to 2.0, an arrangement that reflects their increasing structural connectivity. Considering the silicate component of minerals, the range of composition of the sheet silicates completely overlaps the compositional ranges of framework silicates and most of the chain-ribbon-tube silicates.

Resumo:

Polycrystalline properties of perovskites can induce the growth of different nanostructures, thanks to their facile fabrication. In this work, the CsPb2Br5 perovskite grains were used as templates to induce the growth of the ring-like structures on a SiO2/Si substrate. Owing to the oxidation of the volatile PbBr2 originated from the decomposition of CsPb2Br5, the grain boundaries of perovskites are prone to reaction with SiO2, which leads to the formation of Pb-silicate glass at high temperatures. The quasi-circular grain structure of CsPb2Br5 defines the final dimension of the Pb-silicate glass ring-like structures. X-ray photoelectron spectroscopy (XPS) measurement results reveal the formation and composition of the Pb-silicate glass ring-like structures converting from the halide perovskite film on the SiO2/Si substrate. Furthermore, these ring-like structures can extend to the field of display and pulsed-laser by combining existing techniques.

The effect of alkaline treatment on the destruction process and some surface characteristics of mechanically processed glass discs of lead-silicate glasses C87-2 and C78-4 has been studied. It is shown that the interaction of these glasses with barium hydroxide leads to the removal of silicic acid from the gel surface, which in turn improves the water wettability and optical transparency of the glasses. It is proposed in the production technology of electric vacuum devices, where lead-silicate glasses are used, to use washing with barite water for rapid coagulation of silica gel, which eliminates the appearance of foreign particles on the surface of the glasses.

The investigated ecological glasses with no toxic compounds, such as BaO, PbO, As2O3, As2O5, fluorine, CdS and CdSe in their composition are located in ternary and quaternary oxide systems: ZnO-SiO2-TiO2 and SiO2-R'2O-R''O-R'''O2, where R' is Na or K, R'' is Ca or Mg and R''' is Zr or Ti. The first system contains P2O5, ZnO and TiO2 in order to obtain opal glasses, without fluorine compounds. The second system replaces the barium oxide and lead oxide with potassium, magnesium, zirconium and titanium oxides, for materials like lead free crystals. The raw materials can be replaced by silicate or borosilicate glass waste. The advantages of borosilicate glass waste are: bringing valuable components into recipes (B2O3, CaO, Al2O3), saving raw materials and energy, creating an ecological environment The characteristic temperatures (vitreous transition point, low and high annealing points, softening point) and the thermal expansion coefficient of the glass are presented. The FTIR and Raman spectroscopy provided structural data, such as characteristic vibration maxima for silicon and titanium oxide, and revealed the role of zinc oxide in the vitreous network. The refraction index and UV-VIS transmission are discussed.

Lead silicate glasses are fundamental materials to a microchannel plate (MCP), which is a two dimensional array of a microscopic channel charge particle multiplier. Hydrogen reduction is the core stage to determine the electrical conductivity of lead silicate glass MCP multipliers. The nanoscale morphologies and microscopic potential distributions of silicate glass at different reduction temperatures were investigated via atomic force microscope (AFM) and Kelvin force microscopy (KFM). We found that the bulk resistance of MCPs ballooned exponentially with the spacing of conducting islands. Moreover, bulk resistance and the spacing of conducting islands both have the BiDoseResp trend dependence on the hydrogen reduction temperature. Elements composition and valence states of lead silicate glass were characterized by X-ray photoelectron spectroscopy (XPS). The results indicated that the conducting island was an assemblage of the Pb atom originated from the reduction of Pb2+ and Pb4+. Thus, this showed the important influence of the hydrogen temperature and nanoscale morphological transformation on modulating the physical effects of MCPs, and opened up new possibilities to characterize the nanoscale electronic performance of multiphase silicate glass.

Lead-containing glasses have been used from the ancient time. Recently, due to the possible application in optics, electronics, nuclear techniques, wastes inactivation. the interest in these types of glasses has been renewed. For lead waste inactivation, glasses with high amount of PbO in the composition are required, those exhibiting at the same time a high chemical and thermal stability. Thermal behavior of lead-silicate glasses was examined by differential thermal analysis (DTA). Infrared spectroscopy was used to investigate the structure of the glasses. The spectra were interpreted in terms of the structures of silicate group by comparison with the spectra of other silicate crystals. The DTA and infrared data were correlated with the chemical stability tests.

The present study highlights to the removal of some dangerous pollutants such as lead, arsenic, and fluoride from wastewater. Treatment using a novel polyinorganic coagulants, the eight novel polyinorganic coagulants were prepared, and characterized namely, poly aluminum chloride (PACl) polyaluminum chloride silicate (PAClSi), polyaluminum hydroxy sulphate (PAHS), polyaluminum hydroxy sulphate silicate (PAHSSi), polyferric chloride (PFeCl), polyferric chloridesilicate (PFeClSi), polyaluminum ferric chloride (PAlFeCl), and polyaluminum ferric chloride silicate (PAlFeClSi). The application was carried out for the removal of pollutants from wastewater using these novel polyinorganic coagulants. It was found that the maximum percentages of removal of Pb2+, AS3+, and F- ions from wastewater reached 99.98, 97, and 99%, using novel polyinorganic coagulants PAHSSi, PAlFeClSi, and PAlFeClSi respectively. Therefore, polyinorganic coagulant impregnated with silica was considered as a good coagulant for wastewater treatment due to its low cost and good efficiency in this application, as well as it will solve the problem of water shortage and to sustains a non-conventional water resource.

The measured isotherms of low-temperature nitrogen adsorption-desorption by chrome, vanadium and zirconium silicate adsorbents belong to Type IV (b) of sorption isotherms on IUPAC classification. Such isothermal curves are inherent in mesoporous systems with the M41S type of ordering of the making elements. Increasing рН of sedimentation and metal content lead to amorphization of samples and distortion of a supramolecular lattice with uniform regular geometry and a long-range ordering.

Resumo:

The study of surface hardness, wear resistance, adhesion strength, electrochemical corrosion resistance and thermal conductivity of coatings composed from sodium silicate was prepared using graphite micro-size particles and carbon nano particles as fillers respectively of concentration of (1-5%), for the purpose of covering and protecting the oil distillation towers. The results showed that the sodium silicate coating reinforced with carbon nano-powder has higher resistance to stitches, mechanical wear, adhesive and thermal conductivity than graphite/sodium silicate composite especially when the ratio 5% and 1%, the electrochemical corrosion test confirmed that the coating process of stainless steel 304 lead to increasing the corrosion resistance, where the reinforcing of sodium silicate lead to a significant improvement in the corrosion resistance, the corrosion resistance behavior change depending on the type of reinforcement material, this is consistent with the field test results.

Resumo:

In order to obtain low-cost and excellent adsorption materials, this paper used calcium acetate and water glass as raw materials to synthesis hydrated calcium silicate gel by precipitation method. The performance and structure of hydrated calcium silicate gel were systematically studied by X-ray photoelectron spectroscopy, fourier transform infrared spectroscopy, specific surface area analyzer and scanning electron microscope. Studies have shown that, non-crystal hydrated calcium silicate gel (CSH) were successfully prepared, and the removal rate of lead ion using CSH reached more than 90%. The adsorption process is consistent with the pseudo-second-order kinetic model and Langmuir adsorption isotherm model, and the limit adsorption capacity reaches 263.17 mg·g−1. The acid treatment experiment proved that the adsorption capacity of lead ion using CSH was satisfactory, and the adsorption rate remained at >60% after 5 cycles. The research may provide a low-cost, high-efficiency and high stability adsorbent.

Resumo:

The objective of our investigations consists in the thermal characterization of SiO2-PbO-Na2O vitreous materials in order to establish their properties for applications mainly as sealants. In order to evaluate the vitreous material − metal adherence, the thermal expansion coefficients (α) from experimental and theoretic data were determined. The differential thermal analysis of studied materials give the information about temperatures characteristic to glass transition, crystallization and melting. Dilatometer measurements were performed in air atmosphere in order to establish thermal coefficients of the materials. Softening and flowing characteristic of the vitreous materials were established by heating microscope measurements. The difference between thermal expansion coefficient (α) of the vitreous materials (10.2 × 10−6K−1 and 17.6 × 10−6K−1) and thermal expansion coefficient of the steel substrate OL 38 (10.8 × 10−6K−1) is under 37%. This value is fit for a good adherence between materials.
