Abstract
EN UN PROCESO PARA REDUCIR TINTES EN UNA SOLUCION ACUOSA, SE SUMERGEN UN PAR DE ELECTRODOS EN LA SOLUCION. EL POTENCIAL DE CATODOS SE MANTIENE POR DEBAJO DEL VALOR AL CUAL SE DESARROLLA EL OXIGENO. SE UTILIZA ENTONCES UN AGENTE DE REDUCCION, CUYO POTENCIAL DE REDUCCION-OXIDACION, AUMENTADO POR EL SOBREVOLTAJE DE TRANSFERENCIA DE CARGA REQUERIDO PARA LA REDUCCION DE LA FORMA OXIDIZADA DEL AGENTE DE REDUCCION A LA FORMA REDUCIDA EN EL CATODO, ES INFERIOR AL POTENCIAL DE CATODOS.
