Effective removal of antibiotics from aqueous solutions by a robust activated carbon: experimental and theoretical study.

ABSTRACT: The continuous discharge of antibiotics into water bodies is a potential threat to the ecosystem. We prepared a coal-based activated carbon and characterized it via BET, SEM, FTIR spectroscopy, XRD, TEM, TGA and Raman spectroscopy. Its surface area was 3470 m² g^-1, and its pore size and volume were 1.808 nm and 1.568 cm³ g^-1, respectively. It was evaluated for the removal of moxifloxacin (MOX) and linezolid (LINZ) from water using the Freundlich, Langmuir Temkin and D-R isotherm models and the pseudo-second-order kinetic model. This material removed ∼99.5% of antibiotics, with adsorption capacities of 839 and 832 mg g^-1 for MOX and LINZ, respectively. Thermodynamic parameters i.e. change in Gibb's free energy (ΔG =
