Abstract

Abstract: The extraction mechanism of palladium in chloride system by di(1-methyl heptyl)acetamide(N₅₀₃)has been studied. The compsition of the extracted complex is(CH₃CONR₂H)₂PdCl₄ as determined by the equimolar series method and the slope method. Theextraction mechanism of palladium with N₅₀₃ based on UV-vis spectra is proved to bean anion exchange reaction:2CH₃-CONR₂HCl₀+PdCl₄^2-_a⇔(CH₃CO-NR₂H)₂PdCl_4(o)+2Cl^-(a).

Key words: extraction, mechanism, palladium, di(1-methyl-heptyl)acetamide
