摘要
硫化钠产品的成分比较复杂,硫化钠产品中的杂质分析也很重要,提高硫化钠的质量,开拓硫化钠的新用途,可满足现代高科技发展对硫化钠的特殊要求。介绍了采用分光光度法对其中的氯离子进行了测定,并通过测定回收率来进行验证的分析方法,结果表明该方法测定硫化钠中氯离子的含量准确可靠,非常适用样品的快速测定。
The composition of sodium sulfide product is complex,the analysis of impurities in sodium sulfide products is also impor‐tant.Improving the quality of sodium sulfide and developing new uses of sodium sulfide can meet the special requirements of mod‐ern high-tech development for sodium sulfide.The analytical method of determining chloride ion in sodium sulfide by spectropho‐tometry is introduced and the method is verified by measuring the recovery rate.The results show that this method is accurate and reliable in determining the content of chloride ion in sodium sulfide,and it is very suitable for rapid determination of samples.
