Selective solid-phase extraction of trace copper ions in an aqueous solution using ion-imprinted polymer

Abstract

The study represents preparation of chitosan-based Cu(II) ion-imprinted polymer (IIP) and its utilization for selective solid phase extraction and preconcentration of copper in aqueous and real samples. The IIP was prepared by precipitation co-polymerization. The prepared IIP was characterized by different morphological and elemental analytical techniques such as, FT-IR, SEM/EDS, XRD, TGA, and ICP-OES. Then, prepared material was used for extraction of Cu(II) by optimizing different extraction experiments such as effect of pH, sorbent dosages, and contact time. The results showed successful preparation of an ion-imprinted polymer and optimization of extraction parameters for Cu(II) extraction in aqueous and real samples.
