摘要
本文介绍了延长过磷酸钙熟化时间脱除其水溶性氟，还介绍了添加电由Ｎａｓ，Ｎａ２Ｏ·ＭＳｉＯ＿２、絮凝剂等物质组成的复合剂，脱除过磷酸钙水萃取液中氟的研究。结果显示，氟脱净率远远优于传统一钙法中用ＫＣｌ或ＮａＣｌ脱氟￣［１］．提高饲料磷酸氢钙收率约４０％。
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.
