【Abstract】 In this thesis, a new method that removing fluoine from water including fluoride using type of D401 chelating resins was reported. In t his method, the first the resin adsorbs and immobilizes iron(Fe 3+ ), then t he properties of coordination of fluorine ions (F -) and iron cation (Fe 3+ ) in water solution was utilized, the fluoring can be separated between solid_ liquid phases. The test result shows that the 99% of fluor was removed from wat er including fluorine about 10～20mg/L, and fluorine contents in water can fall to below 0 05mg/L, the static saturation adsorbing capacity is 2 7mg F -/g_ R. Other hands, test result shows as well, common_ions in water do not make affe ct to adsorbing fluor ions by the resin. A high selectin in proccss of removing fluorins has been demonstrated.更多还原
