Selected pharmaceuticals removal using algae derived porous carbon: experimental, modeling and DFT theoretical insights.

ABSTRACT: Porous carbon from Laminaria digitata algae activated using NaOH (PCLD@NaOH) was prepared by a chemical activation approach and has been tested for the adsorption of ketoprofen and aspirin molecules. The prepared PCLD@NaOH was characterized using XPS, FTIR, Raman, N₂-physisorption, SEM, acidic/basic character (Boehm), and pH_PZC. The batch adsorption of ketoprofen and aspirin was investigated under different parameters. The adsorption kinetics on PCLD@NaOH were well described by the Avrami-fractional kinetic model and the equilibrium data by Liu isotherm model. The adsorption capacity of aspirin (970.88 mg g^-1 at 25 °C) was higher than ketoprofen (443.45 mg g^-1 at 25 °C). The thermodynamic values indicate that the adsorption of ketoprofen a
