摘　　要：分别通过微波消解法和标准回流法测定废水中COD,并对两组实验数据进行比较。结果表明:传统的回流法操作繁冗,消耗时间长;微波消解法所用时间短,所需试剂少,减少了二次污染,分析精密度高,准确度好,优势明显。通过研究分析,为一线环境监测工作者测定COD提供了更加便捷、可靠的检测方法及依据。COD in wastewater was respectively determined by microwave digestion method and standard reflux method,and two sets of experimental data were compared and analyzed.The results showed that the traditional reflux method was cumbersome and consumed a long time;the microwave digestion method took less time,required fewer reagents,reduced secondary pollution,and had high analytical precision,good accuracy,and obvious advantages.The research and analysis can provide a more convenient and reliable detection method and basis for front-line environmental monitoring workers to determine COD.
