摘要
对比试验证明，铬酸钡分光光度法测定脱硫气中微量Ｈ２Ｓ含量的准确度完全能满足生产控制分析的需要。在色谱仪发生故障的情况下，采用该法进行测定，保证了装置的正常运行。
Comparative tests have proved that the accuracy in the determination of trace H2S content in the desulfurized gas by barium chromate spectrophotomerty can fully meet the requirements for production control analysis In case the chromatograph fails, the use of this method for determination ensures the normal operation of the unit
