ABSTRACT:
A method for enhancing generation of chlorine dioxide from an aqueous medium containing a chlorine dioxide precursor which comprises contacting the aqueous medium with a catalytic amount of a catalyst selected from the group consisting of a transition metal, a transition metal oxide and mixtures thereof for a period of time effective to generate chlorine dioxide. The transition metals and transition metal oxides which may be employed as the catalyst to enhance the generation of chlorine dioxide are the transition metals of Group 5B, 6B, 7B and 8 of the Periodic Table of Elements.
