Addition of metal chelates to the liquor in a wet stack gas scrubbed to improve removal efficiency of both NO and SO/sub 2/ may provide a new environmental control technology without requiring major capital modification to existing power plants. Criteria for an effective metal chelate additive include large absorption capacity and rapid binding rate for NO and rapid regeneration of metal chelates from nitrosyl metal chelates by reaction with absorbed SO/sub 2/ in aqueous solutions. The thermodynamics and kinetics of chemical reactions involved have been obtained and laser Raman spectroscopy has been used to identify reaction products and intermediates. These results have been used to predict optimum scrubber design and performance for desulphurizationn and denitrification of flue gases.
