摘要
采用电感耦合等离子体发射光谱仪(ICP-AES)同时测定六氟磷酸锂电解液中钠、钾、钙、铁、铜、铬等多种元素,回收率在97.3%～104.1%之间,线性相关系数大于0.999,相对标准偏差在0.02%～0.66%。该方法分析速度快,灵敏度高,重现性好,适合六氟磷酸锂电解液中杂质元素的检测。
This paper discussed the determination of Na, K,Ca.Fe,Cu,Cr etc. in LiPF6 electrolyte with ICP-AES.The recoveries of these elements were 97.3%-104. 1%,and linearity coefficient was more than 0.999, and the relative standard deviations （RSDs） were 0.02%-0.66%. This method was simple and rapid with good sensitivity. The method had been applied to the determination of trace elements in LiPF6 electrolyte with satisfactory results.
