Continuous adsorption of methylene blue (MB) from aqueous solution was studied by using cellulose acetate butyrate (CAB) and poly(L-lactic acid) (PLLA) composite beads. Various parameters such as PLLA composition (0 wt.% and 30 wt.%) and flowrate (7, 13, 23 ml/min) were applied in this experiment. Three different kinetic models, such as Adam-Bohart, Thomas, and Yoon Nelson were applied to the experimental data to analyze the column performance and predict the breakthrough curve of MB adsorption onto adsorbent beads. The value of adsorption capacity increased with the increase of flowrate. The highest maximum capacity was reached by adsorbent of pure CAB (0 wt.% of PLLA) at flowrate of 23 mL/min. Statistical methods such as Sigma Squared Error (SSE), Sigma Absolute Error (SAE) and percentage error were utilized to evaluate the obtained prediction data with the experimental data and to find out the fitted kinetic model for this continuous adsorption. The prediction results indicated that Thomas and Yoon-Nelson models fit well to the experimental data based on the correlation coefficient and error analysis.
