Abstract—Extraction of palladium(II) with diacylated triethylenetetramine hydrochloride (with chloroform as
diluent) from hydrochloric acid solutions was studied. Palladium(II) extraction from 3 mol/L HCl solutions
occurs via anion-exchange mechanism. Concentrational constants were calculated and thermodynamic param-
eters of extraction were estimated.
