Abstract: A method is proposed for the extraction of Pd(II) from 1.0 M HCl medium using Cyanex 302 in toluene. Palladium(II) is determined in the organic phase by direct spectrophotometry at 336 nm. Various parameters such as acid concentration, reagent concentration, time and effect of foreign ions were studied. The probable extracted species is determined by the log(D)-log(C) plot. The method is simple, rapid and permits separation of Pd(II) from closely associated metals like Pt(IV), Rh(III), Ru(III), Fe(III) and Ni(II). It has been applied for analysis of Pd(II) in commercial samples. The proposed method is reproducible with a relative standard deviation of ±1.0%.
