Nickel peroxide in the field of organic synthesis is known as a selective catalyst for liquid phase oxidation. Applicability of this catalyst in water or wastewater treatment is examined first by testing the adsorption characteristics of wide variety of organics.
Phenols are found to be effectively removed and then stoichiometric relation of adsorption of phenol to surface active oxygen atom on the catalyst is determined. Also from the rate of adsorption, intraparticle diffusion kinetics is found to be controlled by pore diffusion.
Regeneration of spent catalyst by sodium hypochlorite as well as cyclic use of nickel peroxide is examined and found practicable.
