Experimental data have been reported concerning the extraction of trivalent antimony from nitric acid solutions using tributyl phosphate (TBP). A possible mechanism for the extraction of antimony(III) has been determined and the (pre)concentration constant for the process has been calculated. The effect of temperature on trivalent antimony extraction has also been evaluated. The enthalpy value and standard isobar potential and entropy for this process have been determined.
