Abstract

PROCEDIMIENTO PARA LA OBTENCION ELECTROLITICA MASIVA DE ZINC, EN UNA CUBA DE UN SOLO COMPARTIMIENTO CON UN CATODO DE ZINC Y UN ANODO DE HIDROGENO POROSO, A UNA TEMPERATURA ENTRE LA AMBIENTE Y 75 C, CON UN RENDIMIENTO SUPERIOR A 85%. CONSISTE EN PASAR CORRIENTE ELECTRICA A TRAVES DE UNA CUBA COMO LA DESCRITA ANTERIORMENTE, QUE CONTIENE UN ELECTROLITO EN CONTACTO CON AMBOS ELECTRODOS, CONSTITUIDO POR UNA DISOLUCION ACUOSA PURIFICADA DOPADA DE SULFATO DE ZINC Y ACIDO SULFURICO, EN CONCENTRACIONES ADECUADAS, SUMINISTRAR GAS HIDROGENO AL ANODO PARA IMPEDIR LA FORMACION DE OXIGENO ANODICO DURANTE LA ELECTROLISIS; Y MANTENER LAS CONCENTRACIONES DE ZINC Y ACIDO DURANTE LA ELECTROLISIS.
