Abstract
In this work, the removal of aniline blue (AB) and methyl violet (MV) from aqueous  solution using chitosan (Cs) and chitosan/activated carbon biomass prepared from eggplant (CS/ACE) and pomegranate peels (Cs/ACP) was investigated.  The respective Cs/biomass was formed from the carbonized eggplant and pomegranate peels which was activated with 0.1 M ZnCl2 prior to their incorporation.  The dye removal process was studied in batch system with respect to the initial pH, contact time, temperature, adsorbent weight and the initial dye concentration. The results indicated that optimal (AB) and (MV) removal was achieved at pH5 and after 5 h contact time.  The experimental data was best fitted to pseudo-second-order model for both dyes based upon the obtained R2 values. As well, the process followed the Freundlich isotherm model.  The thermodynamic parameters (∆Hº, ∆Sº and ∆Gº) for the prepared adsorbents uptake of both dyes indicated that the process was endothermic and spontaneous for AB, however, it was non spontaneous for MV.
