ABSTRACT The present invention concerns to a cyclic continuous process and for the removal of NO and SO2 from a variety of fluid streams. A fluid stream containing NO and SO2 is contacted with an aqueous solution of a composition having a water-soluble organic polymeric chelate containing a polyvalent metal, e.g ., Fe (11). The NO is catalytically absorbed and in the presence of SO2, the imidodisulfonate is formed. Optionally, a reducing agent, such as sodium hydrogen sulfide, is added to maintain the polyvalent metal in the reduced state. The process next includes removal of the imidodisulfonate formed. The separation of water and low molecular weight materials and products, e.g. molecular weight below 500, usually occurs by ultrafiltration or dialysis, with recycle and re-use of the polyvalent metal chelate.
