| Abstract: | The conditions for synthesis of alizarin red-Schelate resin and for separation and preconcentration of Au, Pt and Pd in geological samples have been investigated in this paper. Experiments show that Au, Pt and Pd in solution are enriched on alizarin red Schelate resin column in pH 1.0 HCl and are eluted with 3% acidic thiourea. The recoveries of Au, Pt and Pd are 94.5%～104.1%. The results obtained by the analysis of a standard sample are satisfactory. It is proved that alizarin red-S chelate resin bear sulfonic group with-SO3H as ion exchanging group can be used for separation and preconcentration of Au, Pt and Pd in geological samples and can be used repeatedly more than 3 times. |
