Abstract
A method for the treatment of waste water by the generation of radicals in the waste water comprises applying to the waste water at least one substance which is capable of providing radicals in the waste water. The substance decomposes by a unimolecular mechanism or by hydrogen abstraction to form a carbon-containing radical on exposure to light or heat.
