摘要
对紫外分光光度法测定水和废水中硫化物的方法进行了研究 ,试验了稳定时间、干扰物质、碱溶液浓度对测定的影响 ,提出了最佳测定条件。该方法检测限为 0 0 4mg/L ,相对标准差为 1 4% ,加标回收率在 91 6 %～ 10 1 9%之间。
The detection of sulfure by UV spectrophotometry in water and waste water was discussed. On the tests of stable time, interference, concentration of basic solution, condition of detection was put forward. The detection limit was 0 04 mg/L, relative standard deviation was 1 4%, and the recovery was 91 6%～101 9%
