The kinetics of extraction of uranium (Ⅳ) from hydrochloric acid solutions with HDEHP in cyclohexane have been investigated using the single drop technique. The effects of the concentrations of U(Ⅳ),H+ and HDEHP on the extraction rate for U(Ⅳ) have been examined. It is found that the extraction rate is proportional to [U(Ⅳ)] and [(HDEHP)2](c)1/2 but there is no effect with hydrogen-icn concentration in the aqueous solution.The extraction rate was found to increase with the increasing...

The kinetics of extraction of uranium (Ⅳ) from hydrochloric acid solutions with HDEHP in cyclohexane have been investigated using the single drop technique. The effects of the concentrations of U(Ⅳ),H+ and HDEHP on the extraction rate for U(Ⅳ) have been examined. It is found that the extraction rate is proportional to [U(Ⅳ)] and [(HDEHP)2](c)1/2 but there is no effect with hydrogen-icn concentration in the aqueous solution.The extraction rate was found to increase with the increasing temperature and the apparent activation energy is 41.7 kJ·mol-1 between 10-40℃.It is suggested that the rate-controlling step may be the chemical reaction of U4+ with HDEHP monomer at the liquid-liquid interface.

The kinetics of extraction of aluminum in the D_2EHPA-H_2RPA-H_2SO_4 system has been studied in a quiescent interface cell (lewis cell) with a well defined interfacial area. It is found that this system has simultaneously two series synergistic effects (kinetic and thermodynamic effects) and interfacial chemical reaction has a predominant effect in determining the extraction kinetics.
