Abstract
La presente invenzione riguarda un procedimento per la depurazione di acque contenenti ioni bicarbonato, inquinate da contaminanti organici. Questo procedimento consiste nel sottoporre tali acque ad irradiamento con luce ultravioletta di lunghezza d'onda minore di 400 mm, in presenza di un sistema catalitico consistente in una miscela di ossido di titanio e ossido di zinco, in rapporto in peso TiO2/ZnO compreso 2:1 e 1:2.
