Abstract—This study was designed to investigate the removal of reactive dyes mxiture, C.I Reactive Black 5 (RB5) and C.I Reactive Orange 16 (RO16) using Micellar-enhanced ultrafiltration (MEUF). A cationic surfactant, cetylpyridinium chloride (CPC) was used for the MEUF and its effectiveness was investigated. The critical micelle concentration of CPC was obtained at 0.38 g/L via conductivity method. The diameter of micelles (CPC: 0.6 g/L) obtained at range of 2.3 nm to 6.5 nm diameter. The MEUF process was performed using cellulose acetate membrane with 20,000 MWCO and the surfactant concentration was varied from 0.5 g/L to 1.0 g/L at 400 kPa operating pressure. The results show that the highest dye rejection achieved was 78.0% and 79.2% of RB5 and RO16 for single dye removal while 76.4% and 81.6% of RB5 and RO16 for RB5-RO16 mixture removal from aqueous solution.

Index Terms—Cationic surfactant, critical micelleconcentration, micellar-enhanced ultrafiltration, reactive dye.
