| 中文摘要 | the interfacial tension is measured for cyanex 302 in heptane and adsorption parameters are calculated according to gibbs equation and szyskowski isotherm. the results indicate that cyanex 302 has a high interfacial activity, allowing easy extraction reaction to take place at the liquid-liquid interface. the extraction kinetics of yttrium(iii) with cyanex 302 in heptane are investigated by a constant interfacial cell with laminar flow. the effects of stirring rate, temperature and specific interfacial area on the extraction rate are discussed. the results suggest that the extraction kinetics is a mixed regime with film diffusion and an aqueous one-step chemical reaction proposed to be the rate-controlling step. assuming the mass transfer process can be formally treated as a pseudo-first-order reversible reaction with respect to the metal cation, the rate equation for the extraction reaction of yttrium(iii) with cyanex 302 at ph <5 is obtained as follows:r-f = 10(-7.85)[y(oh)(2)(+)]((a))[h(2)a(2)]((o))(1.00)[h+]((a))(-1.00)diffusion parameters and rate constants are calculated through approximate solutions of the flux equation. |
