Remove of Fluoride from Water Using Dextran-graft-Poly(Hydroxyethyl Methacrylate) Gels Loaded by Divalent Cations

Now a day, fluoride contamination in ground water has been recognized as one of the contaminants for human consumption leading to various diseases [1]. Recently, considerable interesthas been generated in the development of polymeric adsorbents as a tool for removing fluoride from pollutedsystems [2]. On the other hand, utilization of natural resources in developing ion adsorbents (biosorbent) is increasing because of their cost-effective, eco-friendly, and renewablenature. Dextran is a hydrophilic, biocompatible and watersoluble polysaccharide and can be used as fluoride biosorbentafter modifications. In this study, dextran-graft-poly(hydroxylethyl methacrylate) gel were prepared and loaded by some cations (Fe2+, Ca2+ and Mg2+) to remove fluoride from aqueous fluoride solution.
