| 摘 要： | 利用ICP-MS光谱仪，探讨铜质水表中重金属的溶出，分析了水质、浸泡时间、pH值对重金属溶出的影响。各元素在模拟自来水中的溶出量是超纯水的1．5-2倍，溶出量由大到小依次为Cu，Pb，Cr（VI），Cd；一般在0．5d时出现溶出拐点，在4d时达基本饱和；在pH4的酸性水质中，各元素的溶出量为极大值。该方法适于铜质水表中重金属溶出的分析。

| Abstract: | Heavy metals released from the copper meter was investigated by ICP-MS. Effect of water quality, soaking time, pH on stripping was analysed. The elements released in the simulation water was 1.5 to 2 times more than that of ultrapure water. Generally, there was a abrupt change point on half day in the plot of elements release, and there was saturation point on four day. The content of release appeared to be a great value in pH4 acid water. This method was suitable for analysis of heavy metals released from the copper meter. |
