Abstract
SE REVELA UN PROCESO PARA TRATAR SOLUCIONES CATALIZADORAS DE CARBONILACION CON BAJO CONTENIDO DE AGUA, QUE CONTIENEN UN COMPONENTE DE RODIO Y UN COMPONENTE DE METAL ALCALINO, PARA RETIRAR LOS PRODUCTOS DE LA CORROSION METALICA. EL PROCEDIMIENTO COMPRENDE PONER LA SOLUCION CATALIZADORA EN CONTACTO CON UNA RESINA DE INTERCAMBIO DE IONES, PREFERENTEMENTE EN FORMA DE LITIO, Y UNA CANTIDAD SUFICIENTE DE AGUA PARA DISMINUIR LA CONCENTRACION DE IONES DE METAL ALCALINO A FIN DE OPTIMIZAR LA RETIRADA DE PRODUCTOS METALICOS DE CORROSION.
