Abstract

PROCEDIMIENTO DE REDUCCION ELECTROLITICA DE UN ACIDO POLICLOROPICOLINICO. CONSISTE EN HACER PASAR UNA CORRIENTE ELECTRICA DIRECTA A UN CATODO DESDE UN ANODO A TRAVES DE UNA SOLUCION ACUOSA BASICA AGITADA DE ACIDO PICOLINICO. EL CATODO TIENE UNA CAPA SUPERFICIAL DE MICROCRISTALES DE PLATA FORMADOS POR LA REDUCCION ELECTROLITICA DE PARTICULAS DE OXIDO DE PLATA HIDRATADAS COLOIDALES EN PRESENCIA DE UNA BASE ACUOSA. EL CATODO TIENE UN POTENCIAL CON RELACION A UN ELECTRODO DE REFERENCIA DE CALOMELANOS SATURADO DE -0,8 A -1,8 VOLTIOS. LA SOLUCION TIENE UNA TEMPERATURA ENTRE 5 Y 60 GC. EL PH ES DE, AL MENOS, 13 Y CONTIENE, AL MENOS, 0,085 AMPERIOS/CM. CUADRADOS DE SUPERFICIE DE CATODO.
