Research on Workplace Air Nitrogen Oxide Spectrophotometric Method
In order to further explore the accurate determination method of nitrogen oxides in the workplace air,the atmospheric environment of a certain fertilizer plant workplace was taken as the research object.Referring to the relevant requirements of HJ479-2009 Determination of Nitrogen Oxides in Ambient Air-Naphthylethylenediamine Hydrochloride Spectrophotometric Method,an experimental method was established,and the accuracy of the method was confirmed through regression analysis.Then,this method was applied to determine nitrogen oxides in the target area.The results showed that this method has relatively high applicability and accuracy in determining nitrogen oxides in the air,and can accurately determine the content of nitrogen oxides,which has certain application value.
