摘要
用 ICP- AES法同时测定饮用水源中的 Cu、Mn、Pb、Cd、Zn等重金属元素 ,具有基体效应小、测量范围宽等优点。检出限为 0 .2— 4 .0 μg/ L,回收率为 91.5 %— 10 3.9% ,相对标准偏差为 0 .2 9%— 1.5 % ,测定密码样与实际样品 ,结果令人满意。
Copper, manganese, lead, cadmium and zinc in drinking water were simultaneously determined by ICP AES. This method has low reagent effect,and wide detection range. The detection limit of five elements is 0.2-4.0μg/L. The recovery rate is 91.5%-103.9%,and the relative standard deviation is 0.29%-1.5%.The results for determining code samples and real samples are satisfactory.
