Kinetic modelling of the facilitated transport of chromium(VI) by bulk liquid membrane using tri-n-butyl phosphate as carrier

摘要：

A kinetic model is presented which describes the facilitated transport of Cr(VI) ions from acidic solutions through bulk liquid membrane containing tri-n-butyl phosphate(TBP) as carrier. The distribution ratio of Cr(VI) species in feed, liquid membrane and stripping phase(Rf, RLM, Rs) as a function of time t are derived form the model. The model is compared with experimental data and the result is in agreement with calculated values.
