Abstract

column (TCC) has been done. Characterization was also carried out for determining flow regime, shear stress, and energy loss distribution. It was found that featureless turbulent regimes were obtained with the increase of angular frequency ratio at certain values, produces high mixing activity leading to the enhancement of cadmium extraction rate during the process. Much lower shear stress in TCC system compared to that of stirred vessel led to better emulsion stability thus able to perform better extraction efficiency. High cadmium extraction efficiency of almost 100% with membrane breakage in order of 107 makes this method very promising for application in a large scale.
