Using pot experiment, the total arsenic absorbed by Pteris vittata L.from gold roe collected from Guizhou Xingren gold mine was investigated. Arsenic extraction efficiency and effects by five kinds of chelants such as Ethylene diamine tetraacetic acid disodium salt (EDTA-Na2), citric acid (CA), ammonium dihydrogen phosphate (MAP), Sodium bisulfite (NaHSO3) and Sodium bicarbonate (NaHCO3) were assessed. Absorption of As was measured in the fronds and roots of Pteris vittata L.under pot trial condition in which the tested gold ore powder was leached by the above five chelants with the concentrations of 0, 0.05, 0.1 and 0.15 mol•L-1, respectively. The results show that most of the chosen chelants can largely improve the efficiency of arsenic absorption. The leaching efficiency of As in fronds was generally listed in the following order: MAP>EDTA-Na2>CA>NaHCO3>NaHSO3 under the average concentration．With the increase of chelant concentration the As was extracted more and more on MAP and NaHCO3 . The extracting content of As ranged from 5055ug/g to 5974ug/g for EDTA, from3273 ug/g to 4975 ug/g for CA, from 7482 ug/g to 9357 ug/g for MAP and from 3620 ug/g to 5284 ug/g for NaHSO3, from 3401 ug/g to 6378 ug/g for NaHCO3, respectively. The leaching efficiency of As in roots was generally listed in the following order: MAP> NaHCO3>NaHSO3>EDTA-Na2>CA under the average concentration．The extracting content of As ranged from 1862ug/g to 2627ug/g for EDTA, from1494 ug/g to 2347 ug/g for CA, from 2739 ug/g to 3896 ug/g for MAP and from 2064 ug/g to 3373 ug/g for NaHSO3, from 2316 ug/g to 2587 ug/g for NaHCO3, respectively. These results mentioned above show that available As in Guizhou xingren gold mine can be most leached by Pteris vittata L.with the above chelants, especially in MAP treatment. MAP was the best chelants among the four tested chelants, suggesting that it will be useful in chelant-induced phyto-remediation.

Summary We recently reported that during peroxide bleaching, magnesium is substantially more effective when in a complex form with either pulp or a chelant. We also speculated that different magnesium forms affected the catalytic activity of transition metals towards peroxide decomposition to different degrees. As oxygen-delignified pulps still containing lignin were used, it was impossible to separate the catalytic peroxide decomposition by transition metals from the peroxide reaction with lignin, and thus to determine where in the pulp-liquor system magnesium or chelants, or both, were deactivating transition metals. In this paper, we studied the peroxide decomposition kinetics with different modes of addition of the P-stage chemicals in the presence of fully-bleached kraft pulps which are virtually lignin-free, in alkaline filtrates, in P-stage filtrate and in water. We found that most of the peroxide decomposition occurring during a P-stage applied to chemical pulps takes place through interaction with transition metals in the pulp rather than with transition metals in the soluble bulk phase. We also concluded that in any component of a peroxide bleaching system, magnesium is extremely efficient at reducing the rate of peroxide decomposition, while a chelant becomes more valuable when complexing magnesium.

Heavy metals contamination of soil is a widespread global problem. Chelants assisted phytoextraction has been proposed to improve the efficiency of phytoextraction. To study the effects of different chelants on the solubility of heavy metals with time, a batch of soil incubation experiment was conducted. EDTA, EDDS, AES and IDSA of 5 mmol·kg-1 were singly added to the contaminated soil with no chelants addition as control. After 7 days of incubation, the concentrations of water-soluble Pb, Zn, Cu and Cd increased significantly compared to the control. Pb was increased by 158.6, 3.9, 42.2 and 5.3 times respectively, Cu was increased by 45.0, 162.0, 40.0 and 53.6 times respectively, Zn was increased by 6.2, 5.6, 9.4 and 1.5 times respectively, and Cd was increased by 33.5, 3.3, 126.5 and 38.0 times respectively. The results showed that EDDS was more effective for Cu desorption, EDTA was more effective for Pb desorption, and AES was more effective for Zn and Cd desorption, IDSA was more effective for Cd desorption, which was our interesting findings. With the time increasing, the soluble metals with EDTA treatment was increased or not changed, while the water-soluble metals with EDDS, AES and IDSA treatments were decreased significantly. The underlying reason for the results may be the different chemical characteristics of the chelants. EDTA, a persistent chelant, can’t be degraded in the environment, while EDDS, AES and IDSA are biodegradable chelants which were degraded with time increasing and the metals were absorbed to the bulk soil again, resulting in water-soluble metals reduced.

Chelant agents are the mainstay of treatment in copper-associated hepatitis in humans, where D-penicillamine is the chelant agent of first choice. In veterinary medicine, the use of D-penicillamine has increased with the recent recognition of copper-associated hepatopathies that occur in several breeds of dogs. Although the different regulatory authorities in the world (United States Food and Drugs Administration—U.S. FDA, European Medicines Agency—EMEA, etc.) do not approve D-penicillamine for use in dogs, it has been used to treat copper-associated hepatitis in dogs since the 1970s, and is prescribed legally by veterinarians as an extra-label drug to treat this disease and alleviate suffering. The present study aims to: (a) address the pharmacological features; (b) outline the clinical scenario underlying the increased interest in D-penicillamine by overviewing the evolution of its main therapeutic goals in humans and dogs; and finally, (c) provide a discussion on its use and prescription in veterinary medicine from a regulatory perspective.

We conducted a comparative evaluation of different treatments for the bleaching of eucalypt kraft pulps beginning with OP stages. The treatments tested were (1) an acid chelation stage with DTPA (OQP sequence); (2) a hot acid stage (AOP sequence); and (3) a chelant addition into the alkaline oxygen stage ((OQ)P and A(OQ)P sequences). The latter strategy was also studied for environmental reasons, as it contributes to the closure of the filtrate cycle. The OQP sequence leads to the highest brightness gain and pulp viscosity and the lowest peroxide consumption caused by an efficient metals control. Considering that the low biodegradability of the chelant is a problem, the A(OQ)P sequence is an interesting option because it leads to reduced peroxide consumption (excluding OQP) while still reaching high brightness values and similar brightness reversion to OQP prebleaching, with only a viscosity loss of 160 dm3/kg. Therefore, a hot acid stage could be considered when a separate acid Q stage is absent in a prebleaching sequence of Eucalyptus globulus kraft pulps involving OP stages.

Summary In pulp bleaching, while the peroxide-stage chemical charges and the physical operating conditions have been optimized, little attention has been given to the order in which these chemicals are added. We assessed the effects of chemicals, individually and combined, and the effects of the order of addition of these chemicals on peroxide bleaching performance in an acid-treated pulp and in a chelated pulp. We found that adding magnesium to an acid-treated pulp is essential for good peroxide bleaching, while adding magnesium to a chelated pulp provides only a marginal improvement in most additions. But adding magnesium and sodium hydroxide, or sodium hydroxide and magnesium sequentially into a bleaching solution before adding the solution into pulp, causes inefficient peroxide bleaching. This is particularly the case with a chelated pulp. This inefficiency can be avoided if a chelant is added between the additions of magnesium and sodium hydroxide. Magnesium is substantially more effective when in a complex form with either the pulp or a chelant, and the optimum concentration of magnesium for use in peroxide bleaching can be determined by following the peroxide residual.

The nano-TiO2 was prepared by adding surfactant chitosan and sodium dodecyl benzene sulfonate (DBS) under hydrothermal conditions. The influence of chitosan and DBS on the crystal form and photocatalytic properties of TiO2 was discussed. Chitosan acted as the chelant in the reaction, while DBS played the function of preventing aggregation of powder and increasing the degree of crystallization. The fixed calcination temperature was 500°C. The crystallite size could reach about 40.1nm upon the addition of 1g chitosan, and the catalytic efficiency was 51.89%. The crystallite size was about 45.8nm upon the addition of 1g DBS, and the catalytic efficiency was 48.13%. The nano-TiO2 had smaller particle size when chitosan was added under the same reaction conditions.
