A selective method for preconcentration of palladium (II) from sulfuric acid solution using α-
benzilmonoxime-molten benzophenone has been described. Palladium can be extracted
quantitatively into molten benzophenone and determined spectrophotometrically at λmax=
434 nm. Optimization of variables such as ligand concentration, acid type and its
concentration, shaking time and the others were performed. Under selected conditions
Beer's law was obeyed over 0.03–0.60 μg/mL of palladium (1.5–30 μg Pd) with a ...
