Abstract
Micellar enhanced ultrafiltration technique was employed to remove the methylene blue from the aqueous solution. Sodium dodecyl sulfate and regenerated cellulose membrane was used to retain dye from the aqueous stream in stirred ultrafiltration cell. Rejection percentage increases from 75% to 99% with increase in surfactant concentration. Permeate flux remained almost constant throughout the experiment indicating there was no membrane plugging or concentration polarization. Ultrafiltration study was also helpful to determine the important parameters such as distribution coefficient, micelle loading and binding constant for the characterization of micellar solutions and their extraction studies.
