摘要
铅酸蓄电池中硫酸电解液样品采用萃取进行处理,所得试样溶液以硼氢化钾溶液为还原剂,盐酸（7＋93）为载流,用氢化物发生-电感耦合等离子体原子发射光谱法（ICP-AES）测定其中砷元素.在优化仪器的工作条件下,以基体匹配法配置工作曲线标样,有效的消除机体干扰.并用标准加入法做回收试验,测得回收率为99.5％,测定值得相对标准偏差（n=6）为1.5％～1.7％之间.
Samples of the lead-acid storage battery are treated by extraction, and the contents of As in the sample solutions were determined by HG- ICP-AES with KBH4 as reducing and HCL（7＋93）solution as carrying solution. The operational parameters were optimized, and the interference from matrix was eliminated with matrix matching. The proposed method was applied to the analysis of sample of electrolyte was tested by standard addition method values of recovery found were 99.5 % four As. Values of RSD＇s （n=6） were found in ranges of 1.5 %-1.7 % for As.
