ABSTRACT:
Metal complexes and especially nickel EDTA is decomposed by adding an oxidizing agent to an aqueous solution containing metal complexes to define an oxidizable aqueous solution. The oxidizable aqueous solution is then exposed to a source of ultraviolet radiation in the range of from 185-300 nanometers for a period of time sufficient to destroy the complex portion of the metal complex. The remaining metal is recovered.
