Abstract. A new catalytic reaction is proposed and kinetic method developed for the determination of micro amounts of Pd(II) on the basis of its catalytic activity in oxidation of the indigo carmine by hydrogen peroxide in acetate buffer. The sensitivity of the method is 0.4 μg/cm3. The error is below 16% and the method has relatively good selectivity.

KINETIČKO ODREĐIVANJE MIKROKOLIČINA Pd(II) Predložena je nova katalitička reakcija i razrađena nova kinetička metoda za određivanje mikrokoličina Pd(II) na bazi njihove katalitičke aktivnosti pri oksidaciji indigo karmina vodonik-peroksidom u acetatnom puferu. Osetljivost metode iznosi 0,4 μg/cm3. Greška je ispod 16%, a metoda ima relativno dobru selektivnost.
