Abstract Micellar enhanced ultrafiltration (MEUF) is used to ,remove acid dye, from aqueous solution. Cetyl(hexadecyl) pyridinium chloride (CPC) and eosin (molecular weight 691.86) have been taken as cationic surfactant and ,acid dye,, respectively. An organic polyamide membrane of molecular weight cut-off 1000 is used in unstirred batch experiments.

17/7/2013, · If an organic acid, such as acetic acid can desorbs the dye, then the dye has been held by the adsorbent through chemisorption (Arivoli et al. 2009). Desorption process usually done by, mixing a suitable solvent with the dye-saturated substrate and shaken together for fixed time,, until, the dye extract on the solvent, and then using, filtration, to, separate, the adsorbent.
