电感耦合等离子体原子发射光谱测定电池用电解二氧化锰中杂质元素张萍1,贺惠1(1.湖南省衡阳市湖南工学院化学化工系)摘 要:建立了电感耦合等离子体原子发射光谱(ICP-AES)法同时测定电池用电解二氧化锰中Cu,Fe,Pb,Si,P的新方法.对影响其光谱测量的各种因素进行了较为详细的探讨,实验中选择酸度匹配来消除酸度的影响,采用基体匹配校正基体效应.试验结果经t检验发现待测元素之间基本无干扰.方法的检出限为0.003~0.035μg/mL.对无汞碱性锌锰电池用电解二氧化锰进行分析,回收率为97%~104%,RSD......
samples, and this plateau has a tendency to emerge at higher voltage region with increasing Li/Mn ratio. Key words: lithium manganese oxides; spinel; LiMn2O4; Li2MnO3; cyclic voltammetry manganese dioxide (MnO2) served as the raw materials. On preparing Li-doped spinels, raw materials with various nominal Li/Mn ratios (0.45 to 0.70) were mixed and ground carefully, then preheated......
