摘要
在突发性水环境污染事故应急监测中,使用便携式重金属测定仪及时、正确地对重金属污染物含量做出判断,能为污染事故处理、处置和制定恢复措施提供科学决策的依据。使用便携式重金属测定仪PDV 6000 plus快速测定水中镉、铜,得出方法检出限为0.73μg/L和0.75μg/L两个质量浓度的标准溶液平行测定的RSD≤2.0%、实际样品的加标回收率均值为94.1%。
A portable heavy metal analyzer is very useful at environmental accidents. It can fulfill a timely and accurate determination, providing a scientific basis for processing and making recovery program for the accidents. In this paper, we used the portable heavy metal analyzer PDV 6000plus to quickly test cadmium and copper in water. The results showed that detection limit was 0.73μg/L and 0.75 μg/L respectively for Cd and Cu, RSD less than 2.0% , and recovery rate at 94.1% were a- chieved for both elements.
