Abstract
LA PRESENTE INVENCION ES UN PROCESO DE PURIFICACION DE UNA SOLUCION ACUOSA DE CLORURO DE METAL ALCALINO QUE CONTIENE YODO ESENCIALMENTE EN FORMA DE YODURO EN EL QUE SE OXIDA EL YODO HASTA UN GRADO DE OXIDACION 7, ES DECIR E FORMA DE PERYODATO, Y A CONTINUACION SE ELIMINA EL PERYODATO. SE EFECTUA TAMBIEN SIMULTANEAMENTE LA DESTRUCCION DEL AMONIO POR OXIDACION EN NITROGENO MOLECULAR SEGUIDO DE UNA DESGASIFICACION.
