Abstract
A method for the separation of tetrachloroplatinate PtCl42−, and hexachloroplatinate PtCl62−, by solid-phase extraction, using a Dowex 1 × 10 anion exchange resin is proposed. The sequential elution and separation of PtCl42−, and PtCl62− is achieved using selective complexing agents. The eluates, containing Pt(II) and Pt(IV) were analyzed by inductively coupled plasma–atomic emission spectroscopy (ICP–AES). Recoveries of 102% for PtCl42− and 94% for PtCl62− and detection limit of 15 ng g−1 were achieved. Using this method determination of Pt(II) and Pt(IV) in soil samples, spiked with different platinum species was performed. The comparison with GFAAS determination showed a very good agreement.
