In this paper an extraction catalytic kinetic spec-trometric method for the determination of trace palla-dium(Ⅱ)has been described, based on the fact thatpalladium(Ⅱ)can catalyse the oxidation of dithizone by oxygen in the presence of 1,10-phenanthroline asan activator. The detection limit for palladium(Ⅱ)is3.3 × 10 ̄(-9)g/mL,The linear range is from 7.5 × 10 ̄(-9)to 4.0× 10 ̄(-7)G/mL of palladium,The method has beenused to determine palladium in catalysts with satisfac-tory results.

In this paper a new extraction-catalytic kinetic spectrophotometric method for the determination of trace vanadium is studied. The method is based on the vanadium(V ) catalyzed oxidation of diphenylcarbazide by potassium bromate in citric acid medium. The reaction time, concentraction of diphenylcarbazide in aqueous phase and degree of reaction are controlled by extraction equilibrium. The detection limit of this method is 9. 8 × 10-7 g/L(20℃ ) and 8. 3 × 10-7 g/L (25℃). The linear range is 2~800 μg/L (20℃ )...
