摘要:Wheat residue based anion exchanger (WR-AE) was prepared by ETM (epichlorohydrin-triethylamine method), which is the reaction of wheat residue (WR) with epichlorohydrin and triethylamine in the presence of ethylenediamine and N,N-dimethylformamide. Characterization of WR-AE was measured, including BET surface area, SEM, zeta potential, nitrogen content and FTIR analysis. Batch experiments and statistical analysis were conducted to study its ion-exchange property for phosphate from aqueous solutions. Filter bed experiment was conducted for the regeneration test. The characteristic results validated the increased amine groups in WR-AE and its maximum sorption capacity (Q(max), mmol g(-1)) of phosphate was 1.80 +/- 0.06 mmol g(-1). More over, the WR-AE regenerated in both NaCl and HCl solutions can be repeatedly used in several sorption-desorption cycles without any significant loss of the sorption capacities.
