This work was designed to evaluate thesuitability of activated carbon produced from flamboyant pod bark (FPBAC) forthe removal of trichloro-phenol from polluted water. Various concentrations of trichloro-phenol polluted water wasprepared and the adsorption experiments were performed at some selected adsorption factorranges: 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 asignificant effect on the adsorption capacity of FPBAC which was found toincrease with increase agitation, contact time, adsorbent dosage and initialtrichloro-phenol concentrations. The results of thermodynamic studies showedthat the process is exothermic and Langmuir isotherm model with correlationcoefficient (R2) of 0.919 best described the process. The kineticsof the process was best described by pseudo-second order model with correlationcoefficient (R2) value of 0.999.
