Abstract

A Kinetic Study of Aqueous-Phase Reactions of the Nitrate Radical (N(V) with Aldehydes A contribution to subproject CMD Th. Umschlag', H. Herrmann^ and R.

The aqueous particle phase may change the oxidation capacity by either uptake of radicals (lowering the gas phase oxidation capacity) or by heterogenous loss of reactive trace gases (thus enhancing the gas phase oxidation capacity). The kinetics of the degradation of aldehydes in the tropospheric aqueous phase with secondary radical oxidants like NOg is currently not well established. Also the influence of orga
