ABSTRACT:
A method of photodegrading a metallic chelate complex wherein ultraviolet light is directed into an aqueous solution of a metallic chelate to photodegrade the metallic chelate and isolate the metallic portion. The ultraviolet light has a wavelength of no greater than about 210 nm and the method is especially adapted for photodegrading metallic chelates in electroless nickel plating baths and metallic ethylenediamine triacetic acid to recover the metallic portions as well as reduce toxic waste.
