Abstract
PROCEDIMIENTO PARA EL TRATAMIENTO PREVIO DE LA SOLUCION ACUOSA DE ALIMENTACION DE CLORURO DE METAL ALCALINO A UNA CELDA ELECTROLITICA, PARA OBTENER CLORO Y UN HIDROXIDO DE METAL ALCALINO. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE AÑADE UN EXCESO DE CARBONATO SODIO E HIDROXIDO SODICO A LA SOLUCION DE ALIMENTACION SUFICIENTE PARA OCASIONAR LA PRECIPITACION Y SEPARACION DEL CONTENIDO DE DUREZA; SEGUNDA, SE AÑADE ACIDO A LA SOLUCION DE ALIMENTACION TRATADA EN CANTIDAD SUFICIENTE PARA REACCIONAR SUSTANCIALMENTE CON TODOS LOS ANIONES CARBONATO Y ANIONES BICARBONATO PRESENTES, PARA CONVERTIR LA TOTALIDAD DE ELLOS EN DIOXIDO DE CARBONO; TERCERA, SE ELIMINA EL DIOXIDO DE CARBONO EN EXCESO DE DICHA SOLUCION HSTA OBTENER UNA CONCENTRACION INFERIOR A 70 PARTES POR MILLON; Y POR ULTIMO, SE ALIMENTA DICHA SOLUCION A LA CAMARA ANALITICA.
