摘要
探讨了利用微波消解测定水中化学需氧量（ＣＯＤ）的各种条件实验。改进了测定ＣＯＤ的方法，并测定了多种水样。其相对标准偏差为１％～５％。测定结果表明：微波消解具有明显的优点。
A new method for determining COD using the microwave digestion was developed and the digestion conditions were studied. The test results of various water samples showed that the method has the obvious advantages, the ralative standard deviation being 1%～5%.
