Abstract
EN LA PRODUCCION DE CLORATO DE METAL ALCALINO POR ELECTROLISIS DE UN ELECTROLITO QUE CONTIENE CLORURO DE METAL ALCALINO EN UN APARATO DE ELECTROLISIS, SE SEPARAN IMPUREZAS DE SILICIO POR PRECIPITACION CON IONES DE HIERRO. COMO IONES DE HIERRO PUEDEN UTILIZARSE TANTO FE(II) COMO FE(III), Y TAMBIEN MEZCLAS DE LOS MISMOS. LOS IONES DE HIERRO PUEDEN AÑADIRSE AL ELECTROLITO O A UNA SOLUCION ACUOSA DEL CLORURO DE METAL ALCALINO.
