Description 459-467
The preparation and characterisation of a polymeric composite incorporating graphene, hydroxyapatite, and chitosan as an
adsorbent to remove chromium (VI) from wastewater. The FTIR and XRD studies supported the composite's production.
Analysis of surface morphology and heat stability involved TGA and SEM studies. A batch adsorption was run to determine the
efficacy of the adsorbent by varying contact time, adsorbent dose, and pH. The kinetics of the adsorption process were
examined using pseudo-first and second order kinetic models after the equilibrium data had been fitted with the Langmuir and
Freundlich isotherms. The findings showed that pseudo second order kinetics was utilised for the adsorption of Cr(VI) onto
chitosan-grafted graphene/hydroxyapatite (CS-g-Gr/HA) composite.
