Efficient Adsorbent

This study investigated the application of an ion imprinted polymer (IIP) with (3-mercaptopropyl) trimethoxysilane (MPS) functionalized the surface of silica gel as a potential sorbent (IIP- MPS/SiO2) for the selective removal and recovery of Cd2+ from industrial wastewaters. IIP- MPS/SiO2 was prepared by a sol–gel method and characterized by IR. Batch studies were performed to evaluate the adsorption process and it was found that the sorbents were found to adsorb selectively Cd2+ in the presence of Co2+, Ni2+, Zn2+ and Cu2+ interferences in the same medium. IIP-MPS/SiO2 sorbent show the selectivity order under competitive conditions: Cd2+ > Co2+ > Ni2+ > Zn2+ > Cu2+. The removal rate of IIP- MPS/SiO2 sorbent for Cd2+ was about 80 % from synthetic wastewater and mine wastewater spiked with 10, 20 and 50 mg•L-1 Cd2+. This work proved that can IIP-MPS/SiO2 sorbent be used as an efficient adsorbent material for selective removal of Cd2+ from wastewaters.
