Abstract: Closed circuit process for effecting the selective removal of sulfur dioxide values from industrial waste gases or the like wherein a particularly constituted confined solution of mixed ammonium phosphates is exposed to absorbent contact with a sulfur dioxide bearing gas stream in an electrostatic force field followed by a thermally induced desorption of recoverable sulfur dioxide values therefrom and regeneration of the solution preparatory to reexposure thereof to the suflur dioxide bearing gas stream.
