Abstract
LA INVENCION CONCIERNE A UN PROCESO DE DESCONTAMINACION DE LOS TERRENOS CONTAMINADOS POR METALES PESADOS POR TRATAMIENTO POR MEDIO DE SOLUCIONES DE CLORURO DE AMONIO. EL PROCESO DE LA INVENCION ESTA CARACTERIZADO POR LA UTILIZACION DE SOLUCIONES DE CLORURO DE AMONIO CONCENTRADO, ES DECIR QUE CONTIENEN MAS DE UN MOL POR LITRO, ESTAS SOLUCIONES ESTAN ADICIONADAS CON UNA BASE MINERAL PARA ALCANZAR UN PH SUPERIOR A 7. EL PROCESO DE LA INVENCION PUEDE SER UTILIZADO PARA LA REHABILITACION DE LOS TERRENOS CON OBJETO DE UNA UTILIZACION AGRICOLA.
