A Novel Nanofiltration Hybrid System to Control Organic Micro-pollutants: Application of Dual Functional Adsorbent/Catalyst
A homogeneous catalyst, Iron (III)-tetrasulfophthalocyanine (FeTsPc), was immobilized on Amberlite IRA-400 (Amb), a commercial anion exchange resin, by electrostatic interaction. The sorption behaviors and oxidation reactivities of Amb and FeTsPc immobilized Amb were evaluated with Bisphenol-A (BPA), one of Endocrine Disrupting Chemicals (EDCs), which has received great concern due to its adverse effects on human health. FeTsPc immobilized Amb could remove BPA almost completely by adsorption and oxidation when H2O2 was provided as an oxidant while Amb itself could remove BPA to a certain degree by adsorption. The stability of FeTsPc was improved remarkably by immobilizing it on Amb when comparing the stability of the homogeneous FeTsPc in an aqueous solution. Two NF membrane systems including NF-only system (conventional NF) and NF-hybrid system (NF combined with FeTsPc immobilized Amb) were compared in continuous tests.
