Abstract
A method for oxidatively breaking down organic compounds that have low biodegradability and are difficult to oxidize chemically in aqueous effluents, by using a water-soluble peroxide oxidant in the presence of a water-soluble iron or manganese metallophthalocyanine immobilized on an ionic resin consisting of a cross-linked insoluble copolymer derived from a vinylaromatic monomer comprising cationic or anionic groups. The method is particularly suitable for oxidatively decomposing polyhalogenophenols and halogenated hydrocarbons.
