Abstract

EL INVENTO SE REFIERE A UN PROCEDIMIENTO PARA LA DESCONTAMINACION QUIMICA DE SUPERFICIES DE UNOS COMPONENTES METALICOS DE UNA INSTALACION NUCLEAR. LA SUPERFICIE SE TRATA CON UNA SOLUCION ACUOSA QUE CONTIENE UNA FRACCION DE ACIDO OXALICO LIBRE DE ACIDO CARBONICO Y OTRA FRACCION DE ACIDO CARBONICO (3, 6, 8, 11, 12). EL ACIDO CARBONICO APROPIADO ES ACIDO (6) DIHIDROXITARTARICO, ACIDO TARTRONICO (8) O ACIDO MESOXALICO.
