PCT No. PCT/EP94/02688 Sec. 371 Date Jul. 15, 1996 Sec. 102(e) Date Jul. 15, 1996 PCT Filed Aug. 11, 1994 PCT Pub. No. WO95/05894 PCT Pub. Date Mar. 2, 1995A method for removing oxides of nitrogen from gases and liquids by contacting a NOx containing gas or liquid with a polyarylene thioether filter material and a solid oxidizing agent having an electron potential greater than 0.96 V, wherein the solid oxidizing agent oxidizes NO into NO2 which is removed by the polyarylene thioether filter material.
