Abstract |
A method for determination of hydrogen peroxide in the ambient atmosphere is described, using impinger or diffusion scrubber collection of hydrogen peroxide with aqueous-phase analysis by an enzyme-catalyzed fluorescence technique. Interference from ozone at ambient levels is removed by gas-phase titration with excess nitric oxide. The impinger and diffusion scrubber collection techniques are shown to give equivalent results for atmospheric gas-phase hydrogen peroxide with limits of detection of 0.1 ppbv for approximately 60-min and 10-min sampling times, respectively.
