摘　　要：本文通过大量的实验证明对氨基二甲基苯胺光度法测定水中硫化物的吹气时间可由原来的 2 5min缩短到 10min ,与原方法进行对照 ,其精密度和准确度符合要求。从而得出结论 :将吹气时间原方法的 2 5min缩短到 10min ,既节省了时间 。In this article,the author has done a lot of experiments in which the aeration time decreases from 25 minutes of conventional method to 10 minutes in the determination of sulfide in water with p dimethylaminoaniline spectrophotometry.Compared with the conventional method,its precision and accuracy meet the relevant requirements.As a result,this method not only saves the aeration time,but also doesn't affect the precision and accuracy.
