Transcribed Image Text:

A membrane with a thickness of 0.25 µm is used to separate carbamazepine from aqueous solution. The concentration of carbamazepine on one side of the membrane is 5.5 x 10¹ kgmol/m³ while that on the other side is 0.5 x 10¹¹ kgmol/m³. a) For a molar flux of carbamazepine across the membrane of 11.3 x 108 kgmol/m².s at pseudo- steady-state condition, determine the concentration of carbamazepine at the membrane interface. (CO2/PO2/C4) Given: DAB 5.47 x 10-10 m²/s Kc1 1.1 x 10-4 m/s Kc2= 2.6 x 10 m/s. b) Predict the changes in the concentration of carbamazepine at the membrane interface obtained in Part Q2(a) when the molar flux of carbamazepine increases by 50%.
