Activated carbon has been equipped from wood of Hybrid Eucalyptus. Its adsorption capacity in elimination of cadmium from wastewater has been examined during batch adsorption experiments. The adsorption kinetics of this particular carbon for several factors such as adsorbent dosage and contact time of the cadmium were identified. The cadmium adsorption characteristics and the effect of the initial cadmium concentration on elimination capability were also studied. The optimum dosage of Hybrid Eucalyptus wood based activated carbon to remove 80 mg/L of cadmium from aqueous solution was 1.0 g/150 mL and the optimum contact time was 30 min. The isotherm data fit with both Langmuir and Freundlich isotherm models.
