Abstract
Ambient ozone was sampled by the use of passive sampling filter impregnated with ρ-acetamidophenol (AAP) . Ozone reacted with AAP to form 2, 2'-dihydroxy-5, 5'-diacetylamino-biphenyl which was determined by reversed phase high performance liquid chromatograph with fluorescence detection at 420nm. The average concentration of ozone was determined with less than 9.7% relative standard deviation in time weighted average concentration of 19-234 ppb·day. The method was expected to be suitable for long-term monitoring of ozone in ambient air.
