Abstract

Polymer supported core-shell type iminodipropylene glycol functions have been shown to be efficient in chelation with boric acid and can be used for removal of boric acid at ppm levels. Dehydrochlorinated poly(vinyl chloride) (DHPVC) polymeric sorbent was synthesized and graft copolymerization of glycidyl methacrylate(GMA) onto DHPVC was carried out using ATRP method. The epoxy rings in grafted PGMA reacted with excess of ethylenediamine to give an amine containing sorbent. Reaction of the latter with glycidol gives corresponding sorbent with iminopropylene glycol functions. The resulting polymeric sorbent has been demonstrated to be an efficient and regenerable specific sorbent for removal of boron in parts per million (ppm) levels. Kinetics of boron sorption and regeneration of the polymer was investigated.
