A selective method for the extraction and spectrophotometric determination of palladium with
α-benzilmonoxime (BZ) is described. BZ–Pd (II) complex was extracted from acidic aqueous
solution (1.5 M sulfuric acid) into a chloroform layer. Absorbance was measured at 434 nm
and molar absorptivity was found to be about 1.0× 104 cm− 1 mol− 1 liter− 1. Beer's law is
obeyed over the range 0.300 to 13.00 μg ml− 1, with a limit of detection of 0.066 μg ml− 1 Pd
(II). The effects of BZ concentration in chloroform, sulfuric acid concentration, and shaking ...
