摘　　要：研究建立电感耦合等离子体发射光谱(ICP-OES)法同时测定磷酸铁锂中三种主元素锂、铁、磷的分析方法。锂、铁、磷的相对标准偏差均小于0.5%。加标回收率:锂99.8%,铁97.7%,磷100.2%。该方法简单快捷,重复性好,准确性高,可以满足电池材料的快速检测需求。An ICP-OES method for simultaneous analyzing three main elements of lithium iron phosphate was established. The RSD of lithium, iron and phosphor are all lower than 0.5%. The recoveries of lithium, iron and phosphor are 99.8%, 97.7% and 100.2%, respectively. The method is simple and fast. The good repeatability and high accurate method can satisfy the quick determination demand of battery material.
