This paper improved the method of measuring sulfur dioxide in the air by formaldehyde solution absorption method.It can eliminate the interference of nitrogen dioxide in the air by using amino sulfonic acid solution instead of amino sulfonic acid sodium solution to improve the sensitivity of the reaction.This paper also discusses the compound method of parafuchsin hydrochloride.The results show that the improved method has better stability,repeatability and accuracy,reaching the requirements of standard methods.
