Column Experiments for Removal of Copper from Wastewater using Activated Carbon Coated with Tio2 Nanoparticles

Abstract

The study reports application of activated carbon coated with TIO2 nanoparticles to remove Copper from wastewater. The TiO2 nanoparticles are synthesized using sol-gel process and are coated on Granular Activated Carbon (GAC) using Bisphenol resin as adhesive. The synthesized composite material is characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Column experiments are conducted to investigate removal of copper from industrial effluent by varying flow, height and mass of adsorbent. Results showed decrease in the heavy metal and sorption is well explained by Thomas model.
