Abstract

LA INVENCION SE REFIERE A UN METODO DE TRATAMIENTO Y RECUPERACION DE METALES PRECIOSOS, COMO PLATINO, RODIO O PALADIO, CONTENIDOS EN DIVERSAS COMPOSICIONES QUE COMPRENDEN UNA CAPA DE OXIDO U OXIDOS DEPOSITADA SOBRE UN SOPORTE METALICO, EN PARTICULAR CATALIZADORES DE POSCOMBUSTION DE AUTOMOVILES USADOS O AGOTADOS. LA CAPA DE OXIDO QUE CONTIENE LOS METALES PRECIOSOS SE SEPARA DEL SOPORTE METALICO MEDIANTE UNA TECNICA ELECTROQUIMICA DE MANERA QUE LA COMPOSICION QUE SE QUIERE TRATAR FORME UNO DE LOS ELECTRODOS O ESTE EN CONTACTO DIRECTO CON UNO DE LOS ELECTRODOS.
