摘要
本文综述了水质重金属自动在线监测技术的发展,比较了分光光度比色技术和电化学的阳极溶出伏安技术,总结出阳极溶出伏安法具有其检测限低于0.5ug/L、抗共存物质干扰能力强、同时可监测4-6项目的可扩展性以及所用试剂无毒无危害的特点,并结合在昆山市水源地的监测应用,得出阳极溶出伏安法的重金属监测技术可以满足水源地重金属的监测要求,达到对水源水质进行预警的作用。
The development of automatic on-line monitoring technique for heavy metals in water and quality is reviewed in this paper.The comparison between the spectrophotometric colorimetric technique and the electrochemical stripping voltammetry technique is summarized.The results show that the anodic stripping voltammetry has the detection limit lower than0.5ug/L,Anti-coexisting substances have strong ability to interfere with each other and monitor the scalability of4-6projects as well as the non-toxic and harmless characteristics of the reagents used.Combined with the monitoring and application of water sources in Kunshan City,the heavy metal monitoring technique of anodic stripping voltammetry It can meet the monitoring requirements of heavy metals in water sources and achieve early warning of water quality.
