N2 - The adsorption potential of activated carbon derived from Nauclea diderrichii biomass (NDAC) was scrupulously harnessed as a low cost and ubiquitous adsorbent for the removal of greenhouse gas (CO2),
and organic pollutants such as methylene blue (MB) and ibuprofen (IB)
from water. NDAC was fully characterized by scanning electron microscopy
(SEM), thermo-gravimetric analysis (TGA), X-ray diffraction (XRD),
universal attenuated total reflectance-infra red (UATR-IR), Raman
spectroscopy, X-ray photoelectron spectroscopy (XPS), solid state
nuclear magnetic resonance (NMR) and nitrogen gas adsorption–desorption
by Brunauer-Emmett-Teller (BET) technique. This study showed that NDAC
comprises graphitic carbons that had some surface functional groups such
as CC, CO, etc,
which adsorbed these environmental contaminants. The adsorption
equilibrium and kinetic data that the adsorption of these environmental
contaminants formed multilayers (homogeneous surfaces) with the surface
of NDAC. The adsorption mechanism of CO2, MB and IB onto NDAC occurred by via electrostatic attractions and π-π conjugal interactions. The adsorption capacity of NDAC for CO2 was ca. 3.2 cm3.g−1 at 298 K. The Langmuir maximum adsorption capacity, qmax of NDAC for MB and IB was obtained as 35.09 mg.g−1 and 70.92 mg.g−1 at 328 K respectively.
