|Title:||Adsorption of chromium from aqueous solution using Chitosan-g-Graphene/Hydroxyapatite composite|
Sudha, P N
|Abstract:||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.|
