摘要：

A divinylbenzene cross linked polystyrene resin with amine functional groups (Purolite A170) was grafted with glycidol and characterized as a novel sorbent, GLY-resin, for the oxoborate removal from model solutions and post crystallization lye. The sorption behavior of GLYresin was investigated using a batch system. The results showed that the sorption was maximal at pH=9.5. The equilibrium was achieved after 24 h. Calculations based on Lan;,Ymuir model show the monolayer sorption capaciLy q(m)=13 mg/g and the fitted experimental clata chemisorption as a dominating mechanism of boron sorption on GLYresin. Boron removal from the solution containing 5 mg B/L and post:crystallization lye having a 9.1 mg B/L was 99% and 80% respectively. The thermodynamic calculations indicated the spontaneous and endothermic nature of the sorption process. The pseudo-secondorder model adequately described the boron sorption On GLY-resin. Sorption desorption efficiency was 100%, which means the boron sorption at next cycle did not decrease. (C) 2015 The Authors. Published by Elsevier BA/.
