摘要
在水质分析过程中,化学需氧量(COD)测定是一个极为重要的指标。在一定程度上,COD能够反映出水质受还原性物质污染的严重程度,是评价水体污染的主要指标之一,同时也是我国目前水质监测的一个主要参数。探讨并改进了COD行业标准测定方法的实验条件,包括回流时间、酸度影响、氧化剂和催化剂等条件,设计出了氯离子干扰、优化催化剂和优化消解方法三个因素进行混合正交水质COD测定条件的优化。
(COD)determination of chemical oxygen demand is a very important index in the process of water quality analysis.Being one of the main indexes to evaluate water pollution,COD can reflect the severity of water quality pollution by reducing substances to a certain extent,and it is also a main parameter of water quality monitoring in China at present.The experimental conditions of COD industry standard determination method,including reflux time,acidity influence,oxidant and catalyst,were discussed and improved.The optimization of COD determination conditions of mixed orthogonal water quality with Chloride interference、tCatalyst optimization and Digestion method optimization three factors was designed.
