摘要
采用连续流动分析仪测定老挝钾盐矿中的钾含量，并与四苯硼钠重量法进行了比较。结果表明，该方法相关系数达到1．0000，RSD在0．61％～0．88％之间，加标回收率在97．6％～102．4％之间。
The potassium in Laos Potash Mine was determined by Continuous Flow Analyzer,and compared with Sodium Tetraphenylboron. The results showed that the analyzer was able to determine accurately and efficiently the potassium content in Laos Potash Mine. Its coefficient of correlation reached 1. 0000,RSD was at 0. 61% ~ 0. 88% and the recovery of spiked standard at 97. 6% ~ 102. 4%.
