Paper Abstract

A liquid jet technique is used to measure gas phase loss and liquid phase uptake of nitrogen dioxide (NO2) and nitrous acid (HNO2) caused by heterogeneous reactions on liquid surfaces. The experimental results are compared with two-dimensional model calculations. In the case of NO2 the predictions of the model are in agreement with the experimental observations for both gas and liquid phase (i.e., conservation of mass) assuming an effective Henry constant at least eight times larger as the physical Henry constant. In addition the comparison yields a mass accommodation coefficient (alpha) >= 2 * 10-4 for NO2 and (alpha) > 1 * 10-3 for HNO2.
