dc.description.abstractAccess to safe drinking water is one of the most significant concerns of today and foreseeable future. In order to solve this problem, scientists have been working intensively on the development of new technologies. In this study, poly(HEMA)-based porous polymeric membranes were synthesized by UV polymerization method to remove iron contamination in drinking water, which is among the main issues of water purification. The chelating agent desferroxamine (DFO) was covalently bonded to the synthesized poly(2-hydroxyethyl methacrylate-co-glycidyl methacrylate) polymeric membrane. The synthesized DFO-bound poly(HEMA-GMA) polymeric membrane was characterized by FTIR, SEM, elemental analysis, and BET surface area. The optimum removal performance for Iron (III) (Fe3+) ions from an aqueous solution of poly(HEMA-GMA)-DFO membranes was determined in a continuous flow system by varying pH, flow rate, ionic strength, and interaction times. According to the experimental results the maximum adsorption capacity of poly(HEMA-GMA)-DFO membranes for Fe3+ ions was found to be 25.7 mg Fe3+/g at pH:5.0, 1.5 ml/min flow rate, and 100 ppm concentration. The selectivity of the synthesized polymeric membrane for Fe3+ ions was determined as Fe3+>Zn2+ >Ni2+ by adsorption studies performed in the presence of Fe3+ions and Zn2+ and Ni2+ ions. Desorption studies of the membrane system were performed with 0.5 M (ethylenediaminetetraacetic acid) EDTA solution. As a result of desorption and adsorption studies that were repeated 10 times with the same polymer to determine the reuse behavior of the DFO chelator-bound membrane, it was observed that there was no significant decrease in the membrane performance for the removal of Fe3+ ions. Experimental studies revealed that, the use of synthesized poly(HEMA-GMA)-DFO membranes as adsorbents was found to be a promising method for the removal of Fe3+ ions.
