摘要：

A new, simple photometric method for the determination of palladium was described. Palladium was determined photometrically at 600 nm and pH = 5.4 based on its heterogeneous catalytic effect on the reduction of thionine (TN) with hypophosphite (HP) using a probe-type photometer system (variable time method). The influence of reaction variables was discussed. The calibration curve was found linear in the range 0.11–5.55 µg/ml (at 30 °C) and the detection limit was 0.06 µg/ml. The relative standard deviation of the developed method was 1.6% (for 10 replicate determinations of 2.22 µg/ml Pd(II)). The effect of interference from other metal ions and anions was studied. The proposed method was successfully applied to catalysts, Pd–C, Al–Si–Pd (new and used).
