Abstract EN
Magnetic carbon nanocomposite (MCN) was synthesized from waste biomass precursor, pineapple.
The prepared adsorbent was characterized using different instrumental techniques and was used to remove levofloxacin (LEV) from effluents.
The maximum sorption of LEV was observed at pH 7.
Pseudo-2nd-order (PSO) kinetic was found to be the best model that fits well the adsorption kinetics data.
For Langmuir adsorption isotherm, the R2 value was higher as compared with other isotherms.
The Van’t Hoff equation was used for thermodynamic parameters determinations.
ΔS° (standard entropy) was positive and ΔG° (standard Gibb’s free energy) was negative: -0.37, -1.81, and -3.73 kJmol−1 corresponding to 25, 40, and 60°C.
The negative values of ΔG° at different temperatures stipulate that the adsorption of LEV was spontaneous in nature and adsorbent has a considerable affinity for LEV molecules.
The MCN was then utilized in hybrid way by connecting with ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) membranes in series and as a result enhanced permeate fluxes were observed.
The percent retention of LEV molecules was lower with UF membrane and with NF it was 96%, while it was 100% with RO.
For MCN/UF and MCN/NF systems, improvement in % retention was recorded.
