英文摘要	the extraction kinetics of la(iii) from aqueous chloride solutions into n-heptane solutions of bifunctional ionic liquid extractant [a336][ca-12] (tricaprylmethylammonium sec-octylphenoxy acetic acid) was investigated using a constant interfacial cell with laminar flow. the effects of stirring speed, temperature and specific interfacial area on the extraction rate were examined. the results indicate that mass transfer kinetics of la(iii) is a mixed-controlled process influenced by interfacial reaction. on the basis of mass transfer kinetic results in the extraction of la(iii) by [a336][ca-12], the extraction rate equation of la(iii) is proposed in terms of pseudo-first-order constants, which is supported by the measured thermodynamic equations. the mass-transfer kinetic model deduced from the rate controlling step is adequate to interpret the experimental data qualitatively.
