Abstract
UNA SOLUCION ACUOSA CONTENIENDO PALADIO SE PONE EN CONTACTO CON UNA SOLUCION DE UN ANILLO HETEROCICLICO QUE TIENE AL MENOS UN SUSTITUYENTE DEL TIPO - COX, QUE ES, O CONTIENE, UN GRUPO HIDROCARBILO CON AL MENOS 5 ATOMOS DE C. EL COMPUESTO DE ANILLO HETEROCICLICO PUEDE SER UN ESTER DE PIRIDINA DE ACIDO MONODI - O TRI - CARBOXILICO, P.E. EL ESTER BISISODECILO DE ACIDO PIRIMIDINA - 3,5 - DICARBOXILICO. OTROS COMPUESTOS DE ANILLO HETEROCICLICO INCLUYEN AQUELLOS QUE TIENEN UN ANILLO DE PIRIMIDINA, PIRAZINA, PIRIDAZUNA, 1,2,4 - TRIAZOL O IMIDAZOL. EL PALADIO SE EXTRAE EN LA SOLUCION INMISCIBLE EN AGUA MIENTRAS QUE OTROS METALES, ESPECIALMENTE LOS DEL GRUPO DEL PT, PERMANECEN EN LA SOLUCION ACUOSA. EL PA PUEDE SE SEPARADO DE LA SOLUCION INMISCIBLE EN AGUA P.E. USANDO UNA SOLUCION ACUOSA DILUIDA DE AMONIACO.
