A STUDY OF DEFLUORINE TECHNIQUE FOR CALCIUM SUPERPHOSPHATE WATER SOLUBLE FLUORINE

He Yuli(Department of Chemistry Sichuan Continuing Education College of Medical Sciences)  
The author dereloped a technigue for defluorine from the water solulle fluorine moiety of calcium superphosphate by adding a complex defluorine agent which consists of Na2S and Na2O·MSiO2. The result showed that the net-defluorine rate of this method is mueh better than that of the conventional method using KCl and NaCl as the defluorine agent,and the recovery rate of Calcium dibasic phosphate is about 40% higher.
