| 摘 要： | 利用ＫＢＨ４在酸性条件下分解产生的氢气为载气分离水中硫化物，用ＮａＯＨ—Ｈ２Ｏ２溶液吸收Ｈ２Ｓ，并将其氧化为ＳＯ２－４，用离子色谱法测定ＳＯ２－４。方法用于各种水样中硫化物的测定，相对标准偏差为１．５８％，回收率在９０．５％到９８．２％之间。方法适用于水中硫化物的测定

| Abstract: | In an acidic medium KBH 4 was decomposed to produce hydrogen.The sulfide in water was separated by the hydrogen as a supporting gas.The ganerated hydrogen sulfide is absorbed by absorbing sdution of NaOH H 2O 2 and oxidized to sulfate ion.The sulfate ion was determined by Ion Chromatography.The relative standard deviation is 1 58%.The recovery is from 90 5% to 98 2%.The method can be used for the determination of sulfide in water samples. |
