ABSTRACT:
An oxidizable substance and/or a reducible substance is removed from a liquid, such as a liquid industrial waste, by treating the liquid with a composite comprising a fluorine-containing organic cation exchanger and a metal oxide or hydroxide, supported on the cation exchanger. The metal of the metal oxide or hydroxide is selected from manganese and elements of group 1B and group 8 of the periodic table. This treatment is carried out, if required, in the presence of an oxidizing agent, or by using the composite which has previously been treated with an oxidizing agent.
