- Abstract
In this work, chitosan/graphene/TiO2 (CS/GR/TiO2) composites for the removal of Cr(VI) was prepared and characterized by FT-IR, XRD, Raman spectroscopy, TEM, SEM and N2 adsorption-desorption measurements. The composites could retain large specific surface area of graphene, the mesoporous structure of TiO2 and the original function of chitosan. The optimum adsorption conditions for CS/GR/TiO2 composites were investigated. Kinetic data was well fitted by pseudo second-order model. Thermodynamic study indicated that the adsorption process is spontaneous and exothermic. The obtained results indicated that the prepared CS/GR/TiO2 composites has potential application for the wastewater treatment containing Cr(VI).
