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+. en_US DC.subject 選擇性 zh_TW DC.subject 吸附 zh_TW DC.subject 多孔性吸附介質 zh_TW DC.subject 改質 zh_TW DC.subject 重金屬 zh_TW DC.subject adsorption en_US DC.subject mesoporous materials en_US DC.subject modify en_US DC.subject heavy mental en_US DC.subject selectivity en_US DC.title 多孔性吸附介質之表面改質及其對有害重金屬吸附之研究 zh_TW dc.language.iso zh-TW zh-TW DC.title Surface modification of porous materials and application for the adsorption of heavy metal en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
