Abstract

PROCEDIMIENTO PARA LA ELIMINACION DE TIOSULFATOS DE UNA SOLUCION ACUOSA ALCALINA DE LOS MISMOS. COMPRENDE: A) INTRODUCIR UNA SOLUCION ACUOSA DE PEROXIDO DE HIDROGENO, EN UNA SOLUCION ACUOSA DE TIOSULFATOS PROCEDENTE DE LA OXIDACION PARCIAL CON AIRE DE UNA SOLUCION RESIDUAL DE SULFUROS, A UNA TEMPERATURA ENTRE 25JC Y 60JC, EN UNA RELACION PONDERAL PEROXIDO DE HIDROGENO AL TIOSULFATO ENTRE 0,1:1 Y 2:1, A UN PH ENTRE 8 Y 11, DURANTE 15 MINUTOS, Y EN PRESENCIA DE UN CATALIZADOR DE COBRE SOLUBLE EN AGUA, PARA AUMENTAR LA VELOCIDAD Y EL GRADO DE ELIMINACION DE TIOSULFATOS; Y B) MEDIR EL POTENCIAL REDOX DE LA SOLUCION DE A) MEDIANTE UNA SONDA CONSTITUIDA POR UN ELECTRODO DE CALOMELANOS NORMAL, QUE MUESTRA UN DESPLAZAMIENTO POSITIVO A MEDIDA QUE SE ELIMINA EL TIOSULFATO, PARA REGULAR EL NIVEL DE ELIMINACION DE TIOSULFATO EN SOLUCION. EL CATALIZADOR DE COBRE SE EMPLEA EN FORMA DE SULFATO CLORURO, NITRATO DE COBRE Y EN UNA CANTIDAD DE 2 A 20 MG/L DE DISOLUCION.
