伏安极谱法同时检测有色企业工业生产用水中的锌、镉、铅、铜四种离子

Determination of Zn,Cd,Pb,and Cu in production water from Nonferrous Metals Industrial Enterprise by voltammetry polarography

有色企业工业生产用水样品采用吸附溶出伏安极谱仪的悬汞模式(HMDE),使用标准加入法进行检测,Zn、Cd、Pb、Cu这四种元素的检出限均能达到10ng/L,回收率分别为:Cu:100.6%;Zn:100.8%;Cd:92.70%;Pb:104.0%。本研究开辟了在水分析领域中电化学方法检测有色企业工业生产用水中痕量重金属残留的新途径。

The sampled production water from Nonferrous Metals Industrial Enterprise was detected by adsorptive stripping voltammetry(HMDE) using the standard addition method.Detection limits were reached for Zn,Cd,Pb,and Cu at 10ng/L.The recovery rates were as follows:Cu:100.6%;Zn:100.8%;Cd:92.70 %,and Pb:104.0 %.The study establishes an alternative method for detecting trace heavy metal residues in production water from Nonferrous Metals Industrial Enterprise adopting electrochemical methods.
