三元体系KCl-CsCl-H_2O中钾铯分析方法的探究

The analyzing methods of potassium and cesium in the ternary system KCl-CsCl-H_2O

研究比较了重量法和烘干法测定氯化钾、氯化铯单盐以及混合溶液浓度的准确性.得出对于单盐溶液,氯化银重量法、四苯硼钠重量法和烘干法均能相对准确地测定其浓度;对于混合溶液,烘干法与重量法相比更加准确;研究表明烘干法更适于三元体系KCl-CsCl-H_2O中钾铯含量的准确测定.

The accurary with the concentration of the pure solution and the mixture solution of potassium chloride and cesium chloride determined by gravimetric method and drying method were mainly studied and compared.For the pure solution,the gravimetric method and drying method both can determine the concentration relatively accurately;while for the mixture solution,the results determined by drying method are more accurate than that by gravimetric method;the research shows that the drying method is more suitable for the determination of concentration of potassium and cesium in the ternary system KClCsCl-H2O.
