Abstract

In this study, MCM-41, SBA-15, and that modified nanoporous materials were used for absorption of Pb2+ and Cd2+ ions from water. Nano-porous materials properties are characterized by XRD, BET, SEM, and FT-IR, and also, Pb2+ and Cd2+ ions concentration measurements by AAS. According to BET analysis for SBA-15 and NH2-MCM-41 samples, the shape of both sample isotherm is IV type. In this study, the parameters of adsorbent amount, pH changes, and absorption time were investigated. The results show Pb2+ absorption efficiency is more than Cd2+ absorption by synthesized samples. Also, the presence of the Amine group in the structure increases the absorption efficiency. Repeatability of absorption by both samples was performed in four steps and the results show that absorption does not change much, which confirms the repeatability of adsorbents. Also, The X-ray diffraction pattern of the SBA-15 sample shows that the structure is retained after the absorption process.
