Abstract
SE PRESENTA UN METODO Y APARATO PARA MONITORIZACION EN LINEA DE LA CUALIDAD DE UNA SOLUCION DE SULFATO METALICO PURIFICADO. EL METODO CONSTA DE LOS PASOS DE DEPOSICION DEL METAL PROVINIENTE DE LA SOLUCION DE SULFATO METALICO SOBRE UN ELECTRODO DE TRABAJO SUMERGIDO EN LA SOLUCION MEDIANTE EL PASO CONSTANTE DE CORRIENTE EN LA SOLUCION A UNA DENSIDAD DE CORRIENTE EN EL RANGO DE 25 A 150 MA/CM (AL CUADRADO) DURANTE UN INTERVALO DE TIEMPO PREDETERMINADO, DISOLVIENDO EL METAL DEPOSITADO SOBRE EL ELECTRODO DE TRABAJO MEDIANTE LA INVERSION DE LA POLARIDAD DEL POTENCIAL APLICADO ENTRE EL ELECTRODO DE TRABAJO Y UN ELECTRODO CONTRARIO DE MODO QUE PASE UNA CORRIENTE INVERTIDA DE LA MISMA DENSIDAD DE CORRIENTE A TRAVES DE LA SOLUCION HASTA QUE TODO EL ZINC SE QUITE DEL ELECTRODO DE TRABAJO, ESTO SE PERCIBE MEDIANTE UN CAMBIO REPENTINO EN EL POTENCIAL DEL ELECTRODO, OBTENIENDO EL INDICE DE CALIDAD DE LA SOLUCION MEDIANTE EL CALCULO DEL RATIO DE LA DISTRIBUCION DE TIEMPO SOBRE DE TIEMPO DE DEPOSICION, Y RESTRUCTURANDO LA SUPERFICIE DEL ELECTRODO CONTRARIO A TRAVES DE EFECTUAR LA DISOLUCION DEL METAL DEPOSITADO SOBRE EL ELECTRODO CONTRARIO AL FINAL DE CADA MEDIDA.
