| Abstract: | Determination of NO2 in environmental air with passive sampling method was studied.By spectrophotometric 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%and13.8%respectively.The recovery rates were103.9% and 96.0% respectively.This method was simple and could be used widely. |
