Cationic methylene blue(MB+)dye was adsorbed onto a positively charged anodic porous alumina(APA)surface using sodium dodecyl sulfate(SDS)aqueous solutions. We conducted MB+ adsorption by dipping APA in MB+/SDS solutions(method 1)and by two successive dippings of APA in SDS solutions and MB+ solutions(method 2). The two methods produced different adsorption characteristics.
