Investigation of the ion-pair formation of palladium(II) with N-n-octylaniline by solvent extraction from weak organic acid media
نویسندگان
چکیده
The use of N-11-octylaniline in xylene for extraction of palladium(II) from salicylate media is studied. The extraction system is studied as a function of equilibration time, diluent, pH, metal and extractant concentrations. Experimental data have been analyzed graphically to determine the stoichiometry of extracted species. It was found that palladium(II) was extracted into the organic phase by ion-pair formation of the [RR' NH2+ Pd(C7H50 3h"lorg· The method is free from interferences due to commonly associated elements and permits the separation of palladium(II) from other metal ions associated with it. The results are employed in the determination of the metal ions in several synthetic mixtures, alloys and catalyst samples.
