Abstract
Graft copolymer of xanthan gum (XG) and ethylacrylate (EA) has been synthesized by free radical polymerization using potassium peroxydisulfate (KPS) as an initiator in an air atmosphere. The grafting parameters, i.e. grafting ratio and efficiency decrease with increase in concentration of xanthan gum from 0.050Â mg/25Â mL to 0.350Â mg/25Â mL, but these grafting parameters increase with increase in concentration of ethylacrylate from 9Â ÃÂ 10â2 to 17Â ÃÂ 10â2Â MLâ1, and KPS from 15Â ÃÂ 10â3 to 35Â ÃÂ 10â3Â MLâ1. The graft copolymer has been characterized by FTIR, XRD, TGA and SEM analysis. The grafted copolymer was also evaluated as efficient Zn2+ metal binder. The grafted copolymer shows improvement in the stability, solubility as well as their sorbing capacity. Thus graft copolymer formed could find applications in metal ion removal and in drug delivery.
