| 摘 要： | 通过将水样酸化后转化成硫化氢,用氮气带出,被含有定量且过量的铜离子吸收液吸收。分离沉淀后,通过测定上清液中剩余的铜离子,对硫进行间接定量。方法检出限为0.2 mg·L^-1,对实际水样进行分析,加标回收率在90%～95%之间,结果令人满意。

| Abstract: | The water samples was changed into hydrogen sulfide under acidification and was taked out with nitrogen,then was absorpted absorption solution containing quantitative and excessive copper ion.After separating the precipitate,the sulfur was quantified indirectly by detecting residual copperion of supernatant.The detection limit of the method was 0.2 mg/L,the recovery rate was between 90% and 95%,The results for the actual water samples are satisfactory. |
