| description | This article aims to apply an activated carbon on the adsorption of o-cresol
in an aqueous medium. Our work presents a double environmental aspect: On
one hand, a valorization of under-natural products, which is the olive
pomace and on the other hand, the study of the adsorbent efficiency of the
activated carbon resulting from these cores. Activated carbon is prepared
with chemical activation of olive pomace using H3PO4. The characterization
of this porous material has shown a specific surface area equal to 651 m2/g
with the presence of mesopores. Various parameters influencing the
adsorption were optimized, mainly the effect of the contact time, initial
concentration of o-cresol and pH of the solution were studied. The
experimental results show that the sorption equilibrium is reached within
60 min with an adsorption yields of 83.66%. Indeed, the experimental
adsorbed quantity of adsorbent is 3.82 mg/g with o-cresol concentration of
50 mg/L, T = 30°C and pH 2.6 for the better adsorption. The adsorption
process was also studied by examining Langmuir, Freundlich, Temkin isotherm,
and Dubinin-Radushkevich (D-R) isotherm models. The results revealed that
the adsorption system followed the pseudo-second order model and the
Freundlich model. Several thermodynamic factors, namely, the standard free
energy (ΔGads), enthalpy (ΔHads), and entropy (ΔSads) changes, were also
calculated. The results demonstrated that the adsorption process is a
physical and endothermic. The obtained results are interesting, and
applications on other pollutants, in wastewater are in progress. |
