Mass accommodation and chemical reactions at gas-liquid interfaces

The past two decades have seen increased activity in the study of heterogeneous gas-liquid interactions. A range of experimental laboratory techniques were developed that collectively allows measurement of uptake coefficients ranging over 7 orders of magnitude. The experiments yielded kinetics parameters for a large number of reactive and nonreactive gas-liquid interactions. The present review focuses on the kinetics of interactions at aqueous interfaces. The basic phenomena governing interactions of gases with liquids and the resistor model for gas-liquid interactions are presented first followed by the results of experiments with both reactive and nonreactive gas-phase species. Phenomenological treatment of mass accommodation are also briefly described. Furthermore, molecular simulations of interfacial processes related to experimentally observed mass accommodation results are discussed.
