【摘要】 化学需氧量是水质监测的一项重要指标。对化学需氧量标准测定法围绕提高分析速度,缩短回流时间,降低试剂费用而进行的样品消解方法、测定手段、催化剂和氧化剂等方面的改进,及间接预测、在线自动监测研究进展作了简要综述。更多还原

【Abstract】 Chemical oxygen demand(COD) is an important index for water quality monito- ring.This paper reviewed the recent development on the standard measuring method of COD,including sample preparation,testing method,catalyst and oxidant,whose major goal is to improve the analysis speed,decrease the reflux time and lower the cost,as well as the recent development on the indirect forecast and online automatic monitoring.更多还原
