| 摘 要： | 在国内外重金属监测技术的基础上对环境污染事故中重金属（铜、铅、锌、砷、汞、铬、镉）的两种主要快速监测方法进行了研究。研究结果表明：比色法可测试铜、铅、锌、镉、六价铬5种重金属，且精密度与准确度均较好；阳极溶出伏安法（ASV）可测试铜、铅、锌、镉、砷、汞6种重金属，但测定六价铬时偏差较大；除六价铬和铜外，阳极溶出伏安法的测试范围较比色法宽，且检出限较低；阳极溶出伏安法可同时测定镉、铅、铜3种金属，具有较好的适用性。

| Abstract: | Based on the monitoring technologies of heavy metals in the world,two major rapid methods for monitoring the heavy met-als（Cu,Pb,Zn,As,Hg,Cr and Cd）in environmental pollution accidents were studied in this paper.The results showed that：Col-orimentric method can test the content of Cu,Pb,Zn,Cd and Cr （VI）,which reveals a good precision and accuracy;Anodic strip-ping voltammetry（ASV）can test the content of Cu,Pb,Zn,Cd,As and Hg,but has a large discrepancy when applied in testing Cr （VI）;ASV has a larger test range and lower detection limit than colorimentric method with exception of Cu and Cr（VI）;ASV can test the content of Cd,Pb and Cu simultaneously,which also displays a good applicability. |
