Abstract: Porous starch was prepared by replacing ice crystals in frozen starch gel with ethanol using a solvent exchange method. Porous starch was packed in a laboratory scale fixed-bed column to continuous remove Methylene Blue (MB) from aqueous solution through adsorption. The effects of bed height, feed flow rate and initial MB concentration on the breakthrough time were investigated. The breakthrough time decreased with increase in the flow rate and initial MB concentration, and also varied with the change in bed height. Bed Depth Service Time (BDST) model was used to determine the column kinetic parameters, and showed good agreement with the experimental data. © (2014) Trans Tech Publications, Switzerland.
