中文摘要 | studies have been made on the kinetics of ytterbium(iii) with bis-(2,4,4-trimethylpentyl) phosphinic acid (cyanex 272, ha) in n-heptane using a constant interfacial cell with laminar flow. the stiochiometry and the equilibrium constant of the extracted complex formation reaction between yb3+ and cyanex 272 are determined. the extraction rate is dependent of the stirring rate. this fact together with the ea value suggests that the mass transfer process is a mixed chemical reaction-diffusion controlled at lower temperature, whereas it is entirely diffusion controlled at higher temperature. the rate equations for the ytterbium extraction with cyanex 272 have been obtained. the rate-determining step is also made by predictions derived from interfacial reaction models, and through the approximate solutions of the flux equation, diffusion parameters and thickness of the diffusion film have been calculated. |
