Abstract

Abstract: ： The dynamic adsorption characteristics of phosphates on HFO-N and HFO-B composite resins were examined. The fixed bed breakthrough curves, adsorption-desorption performance and the resorbed behavior of the two resins were investigated. The results showed that the penetration time of HFO-N composite resin was longer than that of HFO-B composite resin, and the penetration time was 1 610 h; The treatment volume of HFO-N composite resin was also much higher than that of HFO-B composite resin, and the penetration volume was as high as 8 050 BV; The absorbed amount was 401.48 mg. The phosphate adsorbed in the HFO-B composite resin had a good desorption effect in both desorption process. The desorption of HFO-N composite resin took a long time and the desorption rate was lower. The desorption process of HFO-B composite resin did not affect its subsequent adsorption of phosphate.
