摘要
文章介绍了用四苯硼钠-季胺盐法测定氯化钾中钾离子含量的方法,测定的试样数据与GB6549-1996《氯化钾》中规定的四苯硼钾重量法的数据采用方差分析,得出两方法间无显著性差异,采用该方法测定结果准确,测定速度快,适用于青海格尔木察尔汗盐湖氯化钾生产企业化工分析的需要。
Method of K^＋ measurement in KCl by sodium tetraphenylborate-quaternary ammonium salt method is introduced in the article.The measure data are compared with the data which are measured by sodium tetraphenylborate gravimetric method according to GB 6549—1996 《potassium chloride》 by variance analysis.It is hardly diferent between them.The measure data are accurate and the measure speed is rapid.It can meet the requirement to measure K＋ in KCl for the potassium chloride production enterprise in Chaerhan Salt Lake Area in Golmud of Qinghai.
