摘要
通过试验研究,提出了测定COD的新方法——微波消解-分光光度法。该方法准确度、精密度符合分析要求,与国标中回流法的测定结果没有显著差异。而且采用该方法测定COD可克服回流法、微波消解-滴定法及HACH-COD测定法的操作复杂、耗时长等缺点。
A new analytical method of chemical oxygen demand(COD)——microwave digestion-spectrophotometry was put forward.The precision and accuracy of the new method meet the correlative standard and are very close to that of traditional standard method.The new method is characterized by operating easily and curtailing the digestion and very fit for the analysis on wastewater in environmental monitoring.
