摘要
本文提出采用微波做能源，在常压下，用铬法测定污水中的化学耗氧量，在不加催化剂的条件下，将消解时间从１２０分钟缩短到２０分钟，与电热回流法相比，省去了催化剂，提高了消解的完全程度及成批分析的精密度。并报导了微波炉能量最佳条件及本法与电热回流法的对比测定结果。
This paper presents a new method, in which we determine the oxygen consumption in the sewage by applying microwave as energy source and by means of potassium dichromate method. Without catalysts, the time of treatment is shortened from 120 minutes to 20 minutes. Compared with electrothermal reflux method, the new method needs no catalysts and improves the degree of treatment and the precision of throughput analysis. We also give the optimum conditions of microwave oven energy and the determination results compared with the electrothermal reflux method .
