| Abstract: | The extraction of cadmium(II) by di-(2-ethylhexyl) phosphoric acid dissolved in tetradecane from aqueous chloride and perchlorate solutions has been studied at 25°C. The distribution of the metal has been determined as a function of metal and DEHPA concentrations. Distribution data have been treated both graphically and numerically using the program LETAGROP-DISTR (Acta Chem. Scand. 1971, 25, 1521) and the composition of the extracted species into the organic phase has been determined. The extraction constants for these species are given in Table 1. |
