Determination of platinum and rhodium in Pt-Rh catalysts by TLC in situ
Favourable chromatographic conditions for separation of Pt and Rh were achieved on microcrystalline cellulose with solvent system methylisobutyl ketone - conc. HCl (40+60, v/v) and KI in ethanol as detection reagent ; narow, compact and coloured bands on white background (RF 0.44 for Rh and 0.76 for Pt) were obtained. Convenient conditions for photometry in situ (maximum absorption at 480 nm for Rh and 510 nm for Pt ; range of linearity from 0.06 μg/cm to about 1.5 μg/cm) were also established. Worked out procedure was employed to analyze standard solutions and samples of catalysts (ingots). Results obtained have shown that the method is sufficienthly accurate and suitable for simultaneous quantitative determination of Pt and Rh.
