Highly selective selenite (SeO32−) ion-imprinted polymers (Se(iv)-IIPs) were prepared by the combination of surface ion-imprinting and sol–gel techniques and were then successfully used for the selective removal and preconcentration of Se(iv) in an aqueous solution.

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.
