摘要
采用ICP—MS法对饮用水中的铅进行了分析测定。并进行了载气流量的选择、定量离子质荷比的选择和内标的选择等实验．本实验铅的质荷比选用206，207和208三个加在一起计算。方法的检测限为0．5×10-3mg／L，精密度实验的变异系数为3．25％～7．63％。
A ICP-MS method was described for determination of trace lead in potable water. Some operating charatceristics,including selection of flow of carrier gas,selection of mass charge ratio and selection of interal standard etc. had been studied. The detection limit of this method was 0. 5×10-3mg/L. The variation coefficient of the precision experiment was 3. 25-7. 63%.
