| 摘 要： | 以用时30min的半微量密闭微波消解法取代COD国标测定中的重铬酸钾回流法，改进后的方法精密度小于5．15％，准确度达到102％，COD测定下限为51mg／L。该法节省时间、取样量少、成本低，适用于大批量水样的快速测定。

| Abstract: | A method for rapid determination(in 30 min)of COD by microwave counteracting in closed condition and with semi - trace quantity was developed, which could substitute the national standard method with bichrome. The precision of the method is less than 5.15% , the accuracy is 102% ,and the detection limit is 51 mg/L. It has the advantages of rapidity,using less sample and low cost. It is appropriate to the determination of water sample in great batches. |
