| 中文摘要 | the extraction and stripping kinetics of yttrium(iii) with bis(2,4,4-trimethylpentyl) phosphinic acid (cyanex 272, ha) dissolved in heptane as an acid extractant have been investigated by constant interfacial cell with laminar flow. the experimental hydrodynamic conditions have been chosen so that the contribution of diffusion to the measured rate of reaction is minimized. the plot of interfacial area on the rate has shown a linear relationship, which makes the interface the most probable local for the chemical reactions. at the same time, the extraction thermodynamic and kinetic methods are compared to determine the equilibrium extraction constant. a rate equation and the rate-determining step of the extraction and stripping of yttrium(iii) have also been obtained, respectively. |
