Adsorbtion of Platinum Complex Compounds by Carbon Sorbents

Abstract

Activated carbons and other carbon materials (CM) are known to be selective sorbents for compounds of platinum group's metals (PGM). In particular palladium, ruthenium, rhodium have been found to be extracted effectively by CM from the solutions with great excess of unnoble metals [1, 2]. It is important for practical use for waste and sewage treatment, for development of inserted cata/ysts, for the aims of ana/ysis and purification. Up to now there are few data on the sorption of platinum compounds by carbon materials (CM). This paper presents the results of investigation of sorption capacity and selectivity of carbon materials with different ion-exchange properties as concern variety of complex ions of platinum.
