不同前处理对地表水中铜、锌、铁、锰测定的影响

摘要

Heavy metal pollution is attracting more and more attention recently and becomes the focus of surface water’s monitoring. Different standards have different requirement of pretreatment, which will cause different analysis results. In this study, some methods were used to pretreat the same river’s water, and the impacts of the methods to the analysis of copper, zinc, iron and manganese were compared.%　　重金属污染日益受到关注，成为了地表水监测的重点。不同标准中对地表水前处理的要求不同，从而导致测定结果存在差异，影响测定的准确性。本实验通过对同一河流的水样采取不同的前处理方式，对比各方法对铜、锌、铁、锰等四种元素测定结果的影响。
