Determination of platinum, palladium and rhodium, in aqueous media by means of reversed phase-high performance liquid chromatography (RP-HPLC) after complexation with N,N-dialkyl-N'-acylthioureas

The complexes were successfully separated using conventional Reversed Phase-High Performance Liquid Chromatography (RP-HPLC) and a UV detector. A simple method of complexation of platinum(II) and palladium(II) in acidic, aqueous samples was developed. This method involves the mixing of excess ligand (HL") in acetonitrile with aqueous solutions containing traces of platinum(II) and palladium(II) at room temperature followed by salt-induced phase separation prior to RP-HPLC analysis. In the case of rhodium(III), however, complexation was extremely slow and it has not been possible to include this metal in the complexation procedure for platinum(ll) and palladium(II).
