| Abstract: | The solvent extraction equilibrium for separation of W and Mo was experimentally determined. In acidic medium, D2EHPA (di-2-ethylhexyl phosphoric acid ) was selectedas solvent, sec-octanol as modifier, kerosene as diluent and EDTA as complexing agent, a senes of extraction equilibrium data under different conditions were determined systematically.The effects of various factors on extraction equilibrium were analyzed. Correlation of this extraction system was made and empirical and chemical models applicable to industrial processwere proposed, providing necessary means for industrial designing, engineering optimizationand computer simulation. |
