| 摘 要： | 以K766.490NM为分析谱线，研究了电感耦合等离子体发射光谱（ICP-AES）法测定工业和农业用氯化钾中钾含量的方法。经实际样品测定，RSD为0.3215%。t检验结果证明，该方法与四苯硼钾重量法之间无显著性差异。该方法简便、快速，测定结果准确、可靠。

| Abstract: | Using K 766.490 nm as analytical spectral line, the potassium content in potassium chloride for industry and agriculture application was determined by ICP - AES. Through the actual sample determination, the RSD is 0. 3215%. It was proved by t - test that there is no remarkable difference between this method and potassium tetraphenylborate gravimetric method. This method is convenient and rapid and the result is accurate and reliable. |
