Emulsion liquid membrane modelling for cadmium extraction using a counter rotating Taylor-Couette column (TCC) has been done. Lower shear stress in a TCC system is beneficial in preventing emulsion damage while maintaining excellent extraction efficiency. The study used type II facilitated transport of cadmium based on the immobilized hollow spherical globule model. The investigated parameters were HCl concentration in the external phase (0.05-0.5 M), extraction speed (inner cylinder 600 rpm, outer cylinder: 300-700 rpm), initial feed concentration (75-300 ppm), volume ratio of internal to membrane phase (1/3-1/6), and volume ratio to of emulsion to feed phase (1/4-1/10). The model could explain the experimental data very well with an accuracy of more than 95%. © 2023, Semarak Ilmu Publishing. All rights reserved.
