英文摘要	The extraction behaviors of Ce3+ from nitric acid solution with CMPO dissolved in hydrophobic ionic liquids BmimNTf(2) or BmimPF(6) were studied as functions of solvent, acidity, Ce3+ concentration, salting-out agents, extractant and temperature by batch techniques. The results showed that the extraction efficiency decreases with the increasing of acidity, Ce3+ concentration and temperature, while increased with the increasing of extractant concentration. Salting-out agents had little influence on the extraction. Comparison with BmimPF(6), BmimNTf(2) system showed much higher extraction efficiency. The mechanism for the extraction of Ce3+ from nitric acid solution was discussed and it is suggested that three CMPO molecules are bound to Ce3+ ion to form a coordination compound, Ce3+center dot 3CMPO. Its equilibrium constant and the enthalpy were deduced to be 10(6.49) and -47.29 kJ.mol(-1), respectively.
