The Ru(bpy)/sub 3//sup 2 +/ photosensitized reduction of methyl viologen (MV/sup 2 +/) proceeds rapidly in water-swollen iminodiacetic acid type chelate resin beads which adsorbed both Ru(bpy)/sub 3//sup 2 +/ and MV/sup 2 +/ (RM resin). Photosensitized electron-transfer reaction of Ru(bpy)/sub 3//sup 2 +/ with MV/sup 2 +/ takes place in the resin bead with the aid of polymer-bound iminodiacetic acid (PIDA) as a donor. The back-reaction of Ru(bpy)/sub 3//sup 3 +/ with the methyl viologen radical is prevented by the reduction of Ru(bpy)/sub 3//sup 3 +/ by PIDA. Photosensitized formation of hydrogen peroxide occurs in an aqueous solution containing RM resin and oxygen. Hydrogen peroxide is produced by the reaction of the adsorbed methyl viologen radical with the dissolved molecular oxygen in the heterogeneous system. The photosensitized reaction mechanisms leading to the formation of the methyl viologen radical and hydrogen peroxide in the water-swollen RM resin system are discussed based on the results obtained. 9 figures., 2 tables.
