The objective of this study is to develop an adsorbent that can simultaneously adsorb dichromate and chromium ion. Various concentrations of organic compounds, such as ethyl xanthate, L-cysteine and dodecyl sulfate, containing sulfur atom were used to intercalate Mg-Al layered double hydroxides (Mg-Al LDHs) through a co-precipitation method. The produced adsorbents were used to adsorb dichromate and chromium ion under pH 4 and 5. The adsorbents were characterized by XPS, SEM, FTIR and XRD. The adsorption capacity of target contaminants was calculated by adsorption equilibrium and the possible adsorption mechanism was discussed. The results indicated the Mg-Al LDHs intercalated with ethyl xanthate, L-cysteine and dodecyl sulfate can effectively adsorb dichromate and chromium (III) ion. The adsorption mechanism for chromium ion was regarded as complexation reaction. Because carbonate was found in the interlayer, the adsorption mechanism for dichromate was assumed as anion exchange. The demonstrated the synthesized adsorbents can remove cationic and anionic heavy metal ions. The adsorbents produced by the modification are in addition to the poor adsorption effect obtained after the dodecyl sulfonate intercalation, and the other two anionic organisms can produce high adsorption capacity for the contaminants. For the heavy metal solution at two pH values, the LDHs intercalated by dodecyl sulfonate adsorbs cationic heavy metal contaminants at pH= 5, and the LDHs intercalated by ethyl xanthate removed cationic and anionic heavy metals at pH4 and pH5. The LDHs intercalated by L-cysteine can generate a better effect for the cationic and anionic heavy metal ions at pH5. The overall efficiency of the adsorbent is decrease as the following order: ethyl xanthate-LDHs> cysteine-LDHs> dodecylsulfonate-LDHs.

The main purpose of this study is to remove the toxic compound, Aristolochic Acid, existing in Aristolochia liukiuensis. The scientific and safe biomaterial Carbopol is utilized to remove Aristolochic Acid from natural product to nontoxic or less toxic status. Hence the first step for this research is to develope the methodology for analyzing the amount of Aristolochic Acid existing in Aristolochia liukiuensis. A suitable High Performance Liquid Chromatography (HPLC) method with stationary phase of RP-18 (10 μm) and mobile phase of 66% methanol:34% DI water was developed for Aristolochic Acid identification and quantification. Carbopol, which possesses high molecular weight, is cross-linked water-soluble polyacrylic acids polymer. It was used for the purpose of removing toxic compound, since they both are having polar functional groups. The carboxylic acid functional group of Carbopol was identified by Fourier Transform Infrared Spectrometer (FT-IR). Carbopol, which is available in different viscosity grades, has no effect on the biological activity of the drug while has excellent thickening and suspension effects. Therefore Carbopol polymer is also used in this research for making the control-release formulation. Carbopol and the detoxified natural medicine are blended to prepare gelatinic product. Both stability kinetics and the release pattern were tested for the prepared product. The release rate by disintegration is near 100% after five hours but the dissolution rate is only 10% after three hours. The prepared product is stable under room temperature for five days.

Arsenic is a strong toxic element and drinking arsenic contaminated water for a long period of time will cause blackfoot disease and cancers. There are studies showing the groundwater contains arsenic and its concentration in ranges from 10μg/L up to 1800μg/L in the south western and north eastern coastlines of Taiwan. In this study, manganese oxidant was used to adsorb/oxidize arsenic and treat water contaminated with organic matters. The main substance added to the contaminated water is commercialized standard organic matter that contains different functional groups and extracted organic matter from natural water. By alternating initial pH values with different adding orders and discuss the reaction mechanisms and the influences of natural organic matters to the arsenic removal with manganese oxidants. The results have shown that manganese oxidants and organic matters reacted with As(III)/As(V) reaches equilibrium in two hours. In acidic condition (pH2), small molecules of organic matters are undissociated and may compete with arsenic for adsorption sites on the surface of manganese oxidants. Hence arsenic removal was not improved and restrained. In both neutral condition (pH7) and alkaline condition (pH11), organic matters were dissociated and may have complexes reactions with arsenic follow with adsorption and removal by manganese oxidants, as a result, arsenic is removed. With the purpose of increasing arsenic removal rate in the mixture of manganese oxidants, organic matter and arsenic, addition of lactic acid will increase oxidation rate and arsenic removal rate. However, addition of resorcinol in acidic condition will decrease arsenic removal rate due adsorption site competition. Therefore, orders of arsenic removal rate in different combinations of manganese oxidants, organic matters, and arsenic are: As + org Mn > Mn + As org > Mn + org As. Furthermore, changes in total organic carbon concentration has similar trend with arsenic removal rate. The quantity content trend of functional groups of different sizes of organic matter is <10KD > 10~50KD > 50~100KD. Both As(III) and As(V) removal rates decreased by different molecular sizes of organic matter, and As(III) removal rate increases only under acidic condition.

The main purpose of the research is to develop adsorbent for removal VOC from waste gas. The main factors for consideration are: mechanical strength, regeneration temperature, and auxiliary-fuel. Adsorbent are fabricated to certain shape by screwed-extruding forming machine. Performance of the adsorbent was tested with a continuous fixed-bed reactor and the concentration of VOC was analyzed by HP-GC6890 gas chromatograph. Before the performance test, preliminary experiment indicated that the adsorbed water would reduce adsorption capacity. Therefore, prior to the tests, the adsorbent was purged with dry air at 300 C. Two kinds of binder, nature-clay and pseudo-boehmite (V-5) are used in this study. The experimental results indicated that both clay and pseudo-boehmite can make adsorbent with qualified mechanical strength, but pseudo-boehmite has much higher adsorption capacity.Moreover, with pseudo-boehmite as binder, USY-Zeolite presents the best performance and for the preparation recipe the optimal calcinations temperature is 450 C. Too low temperature (200 C), the adsorbent will be dissolved in water, whereas too high temperature, zeolite crystal in the adsorbent will be destructed, as evidence by SEM and XRD characterization, resulting in a decrease of adsorption capacity.
