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 (R2) of 0.919 best described the process. The kinetics
of the process was best described by pseudo-second order model with correlation
coefficient (R2) value of 0.999.
