Mathematical Modeling of Fixed Bed Adsorption: Influence of Main Parameters on Breakthrough Curve

Dynamic modeling and simulation of fixed bed adsorption process was carried out by explaining the behavior of breakthrough curve parameter. Adsorption of sulfur compound, present in road fuel, has posed a great challenge. A model of fixed bed adsorption of benzothiophene from fuel was formulated with non-ideal plug flow behavior and considered velocity variation along a column. The model was so...

Adsorption of Fe (II) from Aqueous Phase by Chitosan: Application of Physical Models and Artificial Neural Network for Prediction of Breakthrough

Removal of Fe (II) from aqueous media was investigated using chitosan as the adsorbent in both batch and continuous systems. Batch experiments were carried out at initial concentration range of 10-50 mg/L and temperature range of 20–40˚C. In batch experiments, maximum adsorption capacity of 28.7 mg/g and removal efficiency of 93% were obtained. Adsorption equilibrium data were well-fitted with ...
