Batch adsorption of phenol onto physiochemical-activated
coconut shell
coconut
shell activated carbon pelletsThe liquid-phase
adsorption of phenol onto coconut shell-based activated
carbon, CS850A was investigated for its equilibrium
studies and kinetic modeling. Coconut shell was converted
into high quality activated carbon through physiochemical
activation at 850 degrees C under the influence of CO(2)
flow. Beforehand, the coconut shell was carbonized at 700
degrees C and the resulted char was impregnated with KOH
at 1:1 weight ratio. In order to evaluate the performance
of CS850A, a series of batch adsorption experiments were
conducted with initial phenol concentrations ranging from
100 to 500 mg l(-1), adsorbent loading of 0.2g and the
adsorption process was maintained at 30+/-1 degrees C.
The adsorption isotherms were in conformation to both
Langmuir and Freundlich isotherm models.

activated carbonChemical reaction was found to be a
rate-controlling parameter to this phenol-CS850A batch
adsorption system due to strong agreement with the
pseudo-second-order kinetic model. Adsorption capacity
for CS850A was found to be 205.8 mg g(-1).
