摘　　要：介绍了用烘箱消解测定废水COD,烘箱消解分光光度法测定COD代替玻璃仪器回流消解测定COD,通过对两种消解分析样品测定的COD数据比较,结果表明烘箱消解法测定COD较国准法操作简便,速度快,并且检测数据同样准确可靠,完全能够用于实际检测工作中。As comparison of two digestion analysis data, the oven digestion was instead of glass instrument backflow digestion. The results shown that oven digestion was more simple,faster than a national standard method, and testing data as accurate and reliable as same, which can be completely used for actual testing work.
