| Summary: | 碩士 === 國立中央大學 === 環境工程研究所 === 99 === Two mesoporous materials, C16 and C9-106, was modified with N1-(3-Trimethoxysilylpropyl) diethylenetriamine (-3N), 3-Cyanopropyltriethoxysilane (-CN), and 3-Aminopropyltriethoxysilane (-1N). Finally, the removal of heavy metal (Cu2+, Zn2+ and Ag+) using modified mesoporous was investigated.
The aim of the study was to discuss about pore size, surface area, structure of surface, amount of functional group and selectivity of heavy metal.
The mesoporous materials are characterized by ASAP, FTIR, XRD, SEM and EA. Through the adsorption experimental results, we found that the adsorption capacity of modified C9-106 is higher than that of C16. Moreover, among the modification processes to remove Cu2+, Zn2+ and Ag+, the ability of the modified C9-106 by 3N functional silanes was better than that of others. On the other hand, the modified C16 and C9-106 by 3N and CN functional silanes removed the target heavy metal ions in the selectivity order of Ag+ > Cu2+ > Zn2+.
