중금속 흡착을 위한 Mesoporous silica MCM-41의 제조

In this work, Mesoporous silica were prepared from hydrothermal synthesis using gel mixture of tetraethylorthosilcate(TEOS) as silica source and cetyltrimethylammonium bromide(CTMABr) as a template. The surface and structure properties of Mesoporous silica were determined by XRD and TEM. N2 adsorption isotherm characteristics, including the specific surface area (SBET), total pore volume (VT), and average pore diameter (DBJH), were determined by BET. Also, the adsorption amounts of Pb ion on Mesoporous silica were measured using ICP.
