摘要
通过盐酸、硝酸、氢氟酸溶矿、蒸干去氟、过滤、灼烧称重等步骤,快速测定重晶石中的硫酸钡,该方法简单快速,精密度和准确度较理想,适合绝大多数重晶石中的硫酸钡的测定。
By hydrochloric acid, nitric acid, hydrofluoric acid solution mining, evaporated to fluoride, filter, steps such as burning weight, rapid determination of barium sulfate in barite, this law is simple and fast, precision and accuracy better for absolute Most of the barite in the determination of barium sulfate.
