Objective To study adsorption properties of Cu2+ by functionalized mesoporous material MCM-41-(CH2)3NH2-EDTP. Methods The MCM-41 were synthesized by hydrothermal method under alkaline conditions, using sodium silicate as source of silicon and cetyltrimethyl ammonium bromide as template. The modified MCM-41-(CH2)3NH2 was modified by 3-aminopropyltrimethoxysilane(APTS) and ethylsilicate (TEOS), then reacted with EDTP, which succeeded to obtain MCM-41-(CH2)3NH2-EDTP. Assemblies were characterized by XRD, FT-IR and the adsorption of Cu2+ were preliminary investigated. Results The adsorption of Cu2+ by modified-EDTP MCM-41 was better than the adsorption of pure MCM-41. Conclusion After EDTP modified, the adsorption capacity can be improved obviously. The functionalized mesoporous material MCM-41-(CH2)3-EDTP has a promising prospect in inspection of water safety.
