This work describes the application of a new, simple and rapid spectrophotometric method to the determination of palladium in the intermetallides Yb₄₀Pd₃₈Sn₂₂ and Yb₄₀Pd₄₀Ga₂₀. The method is based on the interaction of palladium(II) ions with 5-hydroxyimino-4-imino-1,3-thiazolidin-2-one at pH = 5.0, in a medium of acetate buffer and sodium chloride. The range of the determined concentrations of palladium is 6.0·10^-6-6.0·10^-5 M.
