摘　　要：化学耗氧量(简称COD)是水质综合评价的一项重要指标。采用闭管回流分光光度法测定水样的COD,与标准回流法进行了对照测定实验,并对这两种方法进行F值检验和T值检验,结果表明两法无显著性差异。分光光度法适合于排放废水的测试,试剂用量少、成本低、无需滴定、操作简便,可进行大批量的水样测定,有很强的实用性。Chemical Oxygen Demand (COD) is an important guideline which comprehensively estimates the quality of water. A closed reflux spectrophotometric method(CRSM)for COD is described in this paper and compared with the standard reflux method(SRM). The results obtained are in good agreement with those given by SRM according to F and T statistical inspection. CRSM is suitable to determinate wastewater. It has the advantages of less reagents,low costs, absence of titration,easily operating and adaptation for batch analysis. And CRSM can be widdly applicable.
