DEGRADATION OF A VETERINARY PHARMACEUTICAL PRODUCT IN WATER BY ELECTRO-OXIDATION USING A BDD ANODE

The electrochemical oxidation (EO) treatment in water of Fantetra a veterinary drug widely used in Chile, and its components: oxytetracycline hydrochloride, phtalylsulfathiazole and diphenhydramine, has been carried out at constant current using a BDD/Stainless steel system. First, solutions of each...
