Polystyrene impregnated with beta-diphenylglyoxime, a selective reagent for palladium.
alpha- and beta-diphenylglyoximes impregnated on macroreticular polystyrene (XAD-2) were tested as adsorptive reagents and one of them (the beta-isomer) was found to adsorb palladium in preference to platinum (selectivity factor 20) and nickel (factor > 100).
