摘要
化学需氧量是检验水质污染程度的一项非常重要指标,因此对其检测方法研究一直是人们关注的重点。本文重点介绍了一些新型检测方法,例如:微波消解-分光光度法、高温消解炉-分光光度法、流动注射法、无汞分光光度法等。这些方法都是对传统方法的优化创新,并且都具有污染小、易操作、时间短、能耗低的特点,本文还展望了今后化学需氧量检测的发展方向。
Chemical oxygen demand is a very important indicator for testing the degree of water pollution,so the research on its testing methods has always been the focus of attention.This article focuses on some new detection methods,such as microwave digestion-spectrophotometry,high temperature digestion furnace-spectrophotometry,flow injection method,mercury-free spectrophotometry,etc.These methods are optimization innovations of traditional methods,and all have the characteristics of low pollution,easy operation,short time and low energy consumption.This article also looks forward to the future development direction of chemical oxygen demand detection.
