摘要
海水化学需氧量(COD)是海水中有机污染物的综合指标,是海洋环境监测最重要的项目之一,目前我国海洋环境污染日趋严重,现有的COD测量方法远远不能满足形势的需要,研制开发现场、快速、自动、连续运行的“COD测量仪”势在必行,也是海水COD分析技术发展方向和发展趋势。在国家863计划的支持下,我们研制成功了可用于现场的“臭氧法海水化学需氧量测量仪”。文中介绍了臭氧法海水化学需氧量测量仪的原理、实验室现场试验结果和海试现场情况。大量实验数据表明,该测量仪具有测量快速、结果准确、长时间不需维护等特点。
Seawater chemical oxygen demand is organic contaminant pollutant synthetical indicator, is one of the most important ocean environment monitoring item. At present , ocean pollution of the environment of our country is increasingly serious, COD measurement method can not meet demand. It is imperative to research and develop in-situ-quick-automaticsuccessive analyzer. On the support of national 863 project, we have succeeded in researching and developing Seawater chemical oxygen demand analyzer by ozone oxidation chemiluminescence. Based on experimentation data, these paper further points out great potential and bright future of the analyzer.
