[ I claim:] [1.] A continuous process for the oxidation of oxidizable materials in an aqueous medium comprising adding a hypochlorite solution to an aqueous medium containing at least 500 ppm by weight of oxidizable material and passing the mixture under alkaline conditions through a fixed bed of a particulate catalyst consisting essentially of i) 80-99% by weight of an inert porous support, and ii) a total of at least 1% by weight of an oxidic material selected from nickel oxide, copper oxide, a mixture of nickel and copper oxides, and a mixture of copper oxide and zinc oxide.
