摘要
萤石通过醋酸加热使CaCO3 溶解,再经过滤、沉淀、烘干,以碳酸钠、硼砂混合熔剂熔融,酸浸取后,采用 ICP-AES法测定碳酸钙、氟化钙及二氧化硅、三氧化二铁。此方法精密度好,回收率在 96.0% -101.4% 之间。
The fluorite is heated in CH 3COOH to dissolve the CaCO 3 and then is filtered. The sediment is fused with Na 2CO 3 and Na 2B 4O 7, and then is converted into solution with HCl. Perfect analytic results about CaF 2,SiO 2,Fe 2O 3 can be obtained by ICP AES, the recovery is between 96.0% and 101.4%.
