摘要
试验了微波消解法测定废水中COD的方法,讨论了消解时间、Ag2SO4的用量、氯离子的干扰和混酸介质配比等因素对测定的影响,确定了用该法测COD时的最佳试验条件。该方法测定的废水COD值与回流法测得结果吻合,具用精密度较高、操作费用低、消解速度快等特点。
The rapid determination of COD of wastewater by microwave digestion is tested. The factors,such as digestion time,The amount of Ag2SO4,interference of Cl-and mixed acid ratio,have effects on the determination of COD by microwave digestion. The optimal experimental is ascertained. The result of determination of COD by such method and reflux method are consistent. It has the advantages of high precision,low operation costs and fast digestion speed.
