A process for the disposal of chlorinated organic products, wherein said products are first treated with a sulphonating or nitrating agent, and then are oxidized with an aqueous solution of H.sub.2 O.sub.2, in the presence of Fe(II) ions as catalysts, optionally in association with ions of other transition metals selected from Cu(II), Ti(IV), Mn(II), Co(II), Ni(II), W(IV), Mo(IV), or mixtures thereof. The process leads to a substantially complete elimination of the chlorinated organic products with consequent, considerable reduction of the Chemical Oxygen Demand (COD), and to a high mineralization degree of the organic chlorine atoms.

Process for the disposal of chlorinated organic products by sulphonation

Process for oxidizing organic materials or compounds in aqueous phase, with hydrogen peroxide and in the presence of ferrous ions Fe-(II), and optionally cupric ions cu-(II), carried out under irradiation with artificial visible light.
