| Abstract |
Solvent extraction of Ga(III) with D₂EHPA in sulfuric acid solutions was studied. The distribution coefficient was increased with an increase of pH and the slope of log D vs. pH was 3. The distribution coefficient was increased with decreasing the concentration of gallium ions in aqueous phase and increasing the concentration of D₂EHPA and temperature. The coefficient was higher with D₂EHPA dissolved in kerosene than in benzene. The McCabe-Thiele diagram showed that two extraction stages with the A/O ratio of 1 would be needed to extract gallium ions effectively. |
