Abstract
PROCESSO PER LO SMALTAMIMENTO DI POLICLOROBIFENILI (PCB), IN CUI I PCB, IN CUI I PCB VENGONO TRATTATI CON UN AGENTE SOLFONANTE O MITRANTE, E POI OSSIDATI CON UNA SOLUZIONE ACQUOSA DI H2O2, IN PRESENZA DI IONI DI Fe (II) COME CATALIZZATORI, EVENTUALMENTE IN ASSOCIAZIONE CON IONI DI ALTRI METALLI DI TRANSIZIONE SCELTI TRA Cu (II), Ti (IV), Mu (II), Co (II), N1 (II), W (IV), Mo (IV), O LORO MISCELE. IL PROCESSO PORTA ALL'ELIMINAZIONE PRATICAMENTE COMPLETA DEI PCB, CON CONSEGUENTE ABBASSAMENTO DELLA RICHIESTA CHINICA DI OSSIGENO (COD) A VALORE INFERIORE A 300 mg/l, E AD UN ELEVATO GRADO DI MINERALIZZAZIONE DEGLI ATOMI DI CLORO ORGANICO.
