Abstract
Micellar enhanced ultrafiltration (MEUF) of Ibuprofen (IBU) from aqueous stream was car- ried out by using a 6KDa hollow fiber polysulfone membrane. The surfactant under study was sodium dodecyl sulfate (SDS) and effect of parameters such as initial IBU concentration, varied SDS concentration and operating pressure on the additional resistance and rejections of SDS and IBU were observed. The rejection of SDS and IBU decreased with the increase in operating pressure while the rejection of SDS increased with increasing SDS concentration. The surfactant recovery was attempted by using potassium iodide (KI) as the precipitant. The rejection of IBU and SDS were 90% and 65% respectively with 0.098MPa transmembrane pressure and 100 ppm IBU. More than 80% surfactant was recovered from the retentate stream.
