废气监测二氧化硫过程中遇到的问题及解决方法

Problems and Solutions in the Process of Monitoring Sulfur Dioxide from Exhaust Gas

摘要: 废气的温度、含湿量、高负压和干扰气体都会对定电位电解法监测二氧化硫产生干扰，根据不同的干扰原因提出了不同的解决方法，并推荐应广泛采用非分散红外吸收法对废气二氧化硫进行监测。

Abstract: Temperature, humidity ratio, high negative pressure and interfering gas of the exhaust gas interfere with constant potential electrolysis' monitoring sulfur dioxide. Different solutions are being proposed according to different disturbing causes. And non-dispersive infrared absorption method which is being widely adopted is also recommended to monitor the sulfur dioxide.
