The kinetic behavior of a fixed-bed adsorber can be explained and the characteristic breakthrough curve of the adsorption phenomena can be obtained through mathematical models. In the earlier models, the kinetics is explained using a mathematical model that takes into account of external and internal masstransfer resistances with a nonideal plug flow behavior. The variation of fluid velocity al...

The kinetics in a fixed-bed adsorption system is explained using a mathematical model that takes into account of external and internal mass-transfer resistances with a nonideal plug flow behavior. The variation of fluid velocity along the column is an important aspect, which has not been accounted so far in these models. In the present study, a mathematical model is proposed for explaining the ...

Global environmental pollution challenges can be alleviated if proper disposal and conversion of wastes is promoted. An attempt of converting waste to wealth was made in this study by converting oil palm empty fruits bunch to activated carbon through chemical activation with potassium hydroxide which was used for adsorption of Rhodamine B dye from waste water. Fixed-bed column adsorption system...
