A novel catalytic process is provided for the controlled degradation of organic materials into environmentally compatible products comprising at least carbon dioxide. The process employs a solid catalyst comprising at least one transition element and a peroxide to form a reaction mixture with the organic material which is degraded in the presence of photoenergy absorbable by the catalyst. The catalytic process has multiple applications including the purification of organic solvents; the regeneration of granular activated carbon; the purification of potable water and industrial waste water; and the elimination of organic hazardous and/or toxic substances from collected wastes.

A catalytic process for the degradation of an undesired organic material into environmentally compatible products without need for pretreating the organic material to be degraded, said process comprising the steps of: obtaining the undesired organic material to be degraded in a fluid state; combining said fluid organic material in the presence of water with a solid catalyst comprising at least one transition element and a peroxide as a reaction mixture; and adding photoenergy absorbable by said catalyst to said reaction mixture to yield environmentally compatible reaction products comprising at least carbon dioxide. A catalytic process for the purification of an organic solvent containing dissolved organic material without need for pretreating the organic solvent to be purified, said process comprising the steps of: obtaining an organic solvent containing dissolved organic material as an undesired impurity; combining said impure organic solvent in the presence of water with a solid catalyst comprising at least one transition element and a peroxide as a reaction mixture; and adding photoenergy absorbable by said solid catalyst to said reaction mixture to yield a substantially purified organic solvent and environmentally compatible reaction products comprising at least carbon dioxide. An environmentally compatible process for regenerating granular activated carbon from exhausted granular activated carbon containing organic material, said process comprising the steps of: mixing the exhausted, granular activated carbon with an organic solvent such that the organic material becomes dissolved in said organic solvent and granular activated carbon is regenerated in a form substantially free of adsorbed organic material; separating said regenerated, granular activated carbon from said organic solvent containing dissolved organic material; combining said separated organic solvent with water, a solid catalyst comprising at least one transition element, and a peroxide as a reaction mixture; and adding photoenergy absorbable by said solid catalyst to said reaction mixture to yield an organic solvent substantially free of dissolved organic material and environmentally compatible reaction products comprising at least carbon dioxide.
