生活饮用水输配水设备重金属检测方法研究

Research on Heavy Metal Detection Method of Drinking Water Distribution Equipment

对使用ICP法一次测定生活饮用水输配水设备中铁、锰、铜、锌、砷、镉、铅、银8种元素的迁移量进行可行性研究。结果表示,其线性相关系数均大于0.999,回收率在95.3%~102.2%。结论说明,使用ICP法测定8种元素所得检出限低于GB/T17219标准中规定的重金属析出限量值,可以使用该方法进行检测。

This paper studied the feasibility of using ICP method to determine the translocation of 8 elements,such as iron,manganese,copper,zinc,arsenic,cadmium,lead and silver,in the water distribution equipment for drinking water.The results show that the linear correlation coefficient is greater than 0.999,and the recovery rate is 95.3%~102.2%.The conclusion indicates that the ICP method for the determination of 8 elements is lower than the limit of heavy metal precipitation specified in GB/T 17219 standard,so this method can be used for detection.
