Abstract
The permeation rate of Cd(II) from a dilute aqueous sulfate media using supported liquid membrane technique has been studied. The microporous polypropylene film celgard 2500 was used as solid support for the liquid membrane and TOPS-99 was used as mobile carrier. Effect of different parameters such as stirring rate, Cd(II) concentration in feed solution, pH of feed solution, extractant concentration in membrane phase, and acid concentration in strip solution on cadmium flux was studied. It was observed that stirring speed of 500 rpm was sufficient to minimize the resistance due to aqueous boundary layer. Cadmium flux, J Cd(II) increases with increase in pH of feed solution from 3.0 to 6.0 as well as with increase of cadmium concentration in feed solution. Also with increase in TOPS-99 concentration in membrane phase up to 100 mol/m3 J Cd(II) increases and then becomes constant.
