| 摘 要： | 本文采用NaOH、EDTA和三乙醇胺混合溶液吸收空气中H2S3然后直接对吸收液进行示波段谱测定。方法的线性范围为0．003-5．0ppm，最低检出浓度为3ppb，相对标准差为1．2～2．7％，回收率为91．4～104．6％。应用本法测定了11份空气样品，测定结果与亚甲基蓝比色法一致。

| Abstract: | Hydrogen sulfide in air was absorbed in a solution of NaOH-EDTA-trie-thanolamine and then determined directly in the same system by oscilloplarographp.The peak current was directly proportional to the concentration of sulfide in the range of 0.003-5.0 ppm.The detection limit was 3 ppb, and the relative stan dard deviation and recovery were 1.2-2.7} and 91.9-104.600, respectively. The propo the sed method was applied to 11 of atmospheric samples and in good agreement with methlyene blue method. |
