摘要
采用空气-乙炔火焰原子吸收法测定了LiFePO4/C复合正极材料中的锂含量,选用了硝酸作为测定介质,考察了共存离子Ni2+、Co2+、Mn2+、Fe2+、PO43-的干扰情况,并进行了方法的精密度与回收率实验。结果表明:该方法操作简单,准确度高,能用于实际样品分析。
Li＋ content of LiFePO4/C composite was determined by air-acetylene flame atomic absorption spectrum method.Nitric acid was chosen as medium of determination,the influence of coexisted ion which contained Ni^2＋,Co^2＋,Mn^2＋,Fe^2＋,PO4^3-was researched and the experiments of precision and recovery were carried on.The result shows that this method is simple,easy performing and precise,which can be used in the real sample analysis.
