Abstract

Una solución de tratamiento y un método para eliminar contaminantes de metales pesados y contaminantes de oxianión de una solución acuosa promoviendo la afinidad de precipitar los contaminantes. El método ajusta el pH y el ORP de la solución acuosa contaminada aplicando agentes reductores de FeCI2 y/o NaOH, y usando y aplicando una solución de tratamiento a base de titania de TiO(SO4), H2SO4 y FeSO4.
