Determination of NO2 in environmental air with passive sampling method was studied.By speetrophotometrie method,the relative standard deviation of three kinds of standard solution were between 1.80% and 6.14% ,and the relative standard deviation of two samples were 15.1% andl 3.8%respectively.The recovery rates were103.9% and 96.0% respectively.This method was simple and could be used widely.
