Water pollution causes health‐ and environment‐related problems. Adsorption of pollutants from the bulk is an efficient method for their removal. Modified biopolymers have proven to be effective adsorbents. The biopolymer gum ghatti (GG) has shown good adsorption properties. In this work, GG was grafted with polyacrylic acid (PAA) and loaded with oxidized multiwalled carbon nanotubes (O‐MWCNTs). The resulting GG‐g‐PAA/O‐MWCNT hydrogel was characterized by FT‐IR, XRD, and SEM and its adsorption activity was examined. Sodium diclofenac (SD) was efficiently removed by GG‐g‐PAA/O‐MWCNT. The highest removal efficiency of 92.89 % was achieved at pH 2. The adsorption of SD followed the Langmuir adsorption isotherm and pseudo‐second‐order model.

“…Table 4 shows a list of some of the reported adsorbents and their maximum adsorption capacities (q m ) [54][55][56]. Both PPY-and PANI-coated fabrics show superior adsorption capacities toward SA as compared to chitosan/xylan-coated magnetite and a comparable adsorption capacity for DCF relative to poly(acrylonitrile-co-ethylene glycol dimethacrylateco-vinylbenzyl chloride).…”

The emerging pharmaceutical contaminants diclofenac (DCF) and salicylic acid (SA) pose potential hazards to humans and living organisms due to their persistence in water environments. In this work, the conductive polymers polypyrrole (PPY) and polyaniline (PANI) were successfully coated on cotton fabrics, as confirmed by FTIR and SEM measurements. The coated fabrics efficiently removed DCF at pH 5.3 and SA at pH 4, with removal efficiencies that exceeded 90% and 70%, respectively. Adsorption was rapid for most of the tested contaminant–fabric systems and reached equilibrium within 20–30 min. The best adsorption performance for both contaminants was shown on the PPY-coated fabrics, which yielded adsorption capacities of about 65 and 21 mg/g for DCF and SA, respectively. This could be explained by molecular modeling simulations, which mostly estimated higher total cohesive energy densities for adsorption on the PPY-coated fabrics than on the PANI-coated ones. The adsorption mechanism involved both coulombic electrostatic attractions and non-coulombic van der Waals and π-π stacking. The fabrics could be reused for three adsorption–desorption cycles. Immobilization of the conductive polymers on cotton fabrics provides a facile method for their handling and collection during adsorption and regeneration cycles while maintaining their multi-functionality in adsorbing different contaminants.
