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

Includes bibliographical references. === 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 me...
