A study on mass transfer model for cadmium extraction in emulsion liquid membrane system has been done. Mass transfer in the external phase and emulsion globule, stripping reaction, and diffusion of the complex were taken account into the model. Reaction and chemical equilibrium of the process were also considered. The partial differential equation was numerically solved using MATLAB software. Effect of some parameters such as acid concentration in the external phase, extraction speed, volume ratio of emulsion to feed phase, volume ratio of internal to membrane phase, and initial concentration to the extraction process were investigated and compared to the model. The model prediction can agree very well with the concentration profile of cadmium in each phase. © 2013 Penerbit UTM Press. All rights reserved.
