Abstract
This study aimed to create activated carbon thin film (ACTF) as a hybrid nanocarbon
via a simple and efficient method through a single-step mixing process using thermal
functionalization techniques. Then, magnetite and nanoscale zerovalent iron (Fe0/Fe3O4)
nanoparticles were synthesized by co-precipitation and chemical reduction methods, respectively
within the matrices of the prepared ACTF to produce ACTF/Fe0/Fe3O4 nanocomposite
(MACTF) in three different proportions of Fe0/Fe3O4, producing MACTF-1, MACTF-2, and
MACTF-3. XRD, TEM, FTIR, Raman, BET, BJH, and TGA analyses were used to characterize
the ACTF, and MACTF nanocomposites. from the characterization results, the synthesized
ACTF and MACTF-1 were used as adsorbents for the removal of Phenol (Ph) and p-nitrophenol
(PNP) from aqueous solution. The ability of ACTF and MACTF-1 to remove Ph and PNP was
investigated by batch experiments according to various parameters. It was found that MACTF-1
can significantly increase the removal efficiency of Ph and PNP compared to the pristine ACTF
and a synergetic effect occurred between ACTF and Fe0/Fe3O4 for Ph and PNP removal. The
adsorption kinetics, isotherm and thermodynamics also have been evaluated. The studies on the
adsorption revealed that the adsorption process obeyed the Pseudo-second order kinetics model,
and the rate-limiting step might be chemical sorption. And the Freundlich isotherm was
applicable to describe the adsorption process. Moreover, Thermodynamic parameters indicated
that the adsorption process was exothermic and spontaneous. Reusability of the prepared ACTF
and MACTF-1 in the adsorption–desorption process were simply done for successive 5 times,
and for MACTF-1 could be easily removed from solution using a hand-held magnet in short
time. Furthermore, ACTF and MACTF-1 exhibited effective implementation to remove phenol
with other various pollutants with high concentration from real water samples. This study
confirmed the successful application of ACTF and MACTF-1 as an efficient, eco-friendly, and
sustainable adsorbent at a high level of feasibility for the uptake of hazardous contaminants from
industrial wastewater.
