چکیده
In this research work, activated carbon prepared locally from Thespesia Populnea bark(TPC) was examined for the removal of cobalt (II) from aqueous solution. The main parameters, like effect of adsorbent dosage, Co (II) concentrations, effect of contact time and effect of pH was studied in batch experiments. The experimental results were analyzed by using Langmuir, Freundlich, adsorption isotherm models. The kinetic data well described by the pseudo-first-order kinetic model. The various thermodynamic parameters such as , and were also determined. The activated carbon produced from TPC was successfully employed for removal of cobalt (II) ion from aqueous solution and the technique appears industrially applicable and feasible.
