摘　　要：提出了用高锰酸钾比色法测定气体中H2S含量的方法。考察了介质、温度、进样时间和静置时间等因素对测定结果的影响,确定了适宜的操作条件:在酸性介质中进行,测量温度为80℃,进样时间为8min,静置时间为10min。实验结果表明,该法不仅适用于气体中H2S含量的检测,也适合于水溶液中S2-含量的分析。A new method for measuring H_2S content in gas by potassium permanganate colorimetry was studied.The influences of different factors on the measuring results were investigated and reasonable measuring conditions were obtained.The results showed that the method was suitable for measuring H_2S in gas or S^(2-) in waste solution.
