Abstract :This work was designed to evaluate the suitability of activated carbon produced from flamboyant pod bark (FPBAC) for the removal of trichloro-phenol from polluted water. Various concentrations of trichloro-phenol polluted water was prepared and the adsorption experiments were performed at some selected adsorption factor ranges: agitation, 150 – 250 rpm; contact time, 60 – 120 min; adsorbent dose, 0.15 – 0.25 g; and initial trichloro-phenol concentrations, 100 – 200 mg/L. Results of the study showed that the selected adsorption factors has a significant effect on the adsorption capacity of FPBAC which was found to increase with increase agitation, contact time, adsorbent dosage and initial trichloro-phenol concentrations. The results of thermodynamic studies showed that the process is exothermic and Langmuir isotherm model with correlation coefficient (R 2 ) of 0.919 best described the process. The kinetics of the process was best described by pseudo-second order model with correlation coefficient (R 2 ) value of 0.999.Keywords : Flamboyant Pod Bark, Trichloro-phenol, Adsorption, Activated carbon
