Abstract:
This paper reports the study on the D001 changed property resin defluoridation material preparation and ion exchange model 、acid wash 、Fe exchange quantity effect for defluoridation material saturation absorbent quantity ;simultaneity writer disguessed concomitant ion influence for defluoridation effect of FeⅢ)-R and defluoridation mechanism of defluoridation material.Experiment results show that ion exchange model 、acid wash、Fe exchange quantity has definite influence for defluoridation effect , by means of acid wash and dynamic exchange model can prominently improve defluoridation effect of defluoridation material;concomitant ion has not evident influence for defluoridation effect, study ulteriorly opens out the defluoridation mechanism and shows that The absorbent has the advantage of simplicity in operation , easy revivification and is reusable .
