Synthesis of Novel Ion-Imprinted Polymers for Selective Recovery of Mo (VI) from Water

The purpose of this study is to prepare two novels ion imprinted polymers as adsorbent for MoO22+ with high selectivity. Ion-imprinted polymers (IIPs) materials were synthesized by thermallycopolymerizing of methacrylic acid (MAA) or 2-hydroxyethyl methacrylate (HEMA) as monomer,ethylene glycoldimethacrylate (EGDMA) as crosslinking agent and 2,2´-azobisisobutyronitrile(AIBN) as initiator. For MoO2 2+ IIP in the presence of the ion pair complex formed between an inorganic complex of (Mo(VI)-thiocyanate) and tetrabutylammoniun (NR4 +) was precipitated into the aqueous sample and was dissolved into the acetonitrile. The IIP will be used as adsorbent in a batch extraction of Mo ions from water samples. The effects of sampling volume, eluent condition and sample pH on the extraction of Mo ions from water samples were optimized by using chemometric tools (central composite desige (CCD)). The maximum adsorption capacity and therelative selectivity coefficients of imprinted polymer for Mo (VI)/another metal ions will be calculated. The developed method is successfully applied to remove Mo (VI) from diverse matrixin water samples
