Abstract

SE PROPORCIONA UN PROCESO PARA DESTRUIR EL CONTENIDO DE CATALASA DE UNA SUBSTANCIA O MATERIAL. EL PROCESO COMPRENDE LOS PASOS DE PONER EN CONTACTO LA SUBSTANCIA O MATERIAL CON OZONO DURANTE UN PERIODO DE TIEMPO SUFICIENTE PARA DESTRUIR LA ENZIMA CATALASA. LA CANTIDAD DE OZONO CARGADO EN LA SUBSTANCIA O MATERIAL ESTA GENERALMENTE EN EL MARGEN ENTRE 0.01 Y 0.15 % DE PESO, BASADO EN EL PESO DE LA SUBSTANCIA O MATERIAL. EL PROCESO ES PARTICULARMENTE MAS APLICABLE AL TRATAMIENTO DE UNA PULPA FIBROSA CONTAMINADA CON CATALASA QUE SE VA A SOMETER A UN TRATAMIENTO DE BLANQUEO CON PEROXIDO DE HIDROGENO.
