Kinetics Investigation of Cr(VI) Removal by Modified Perlite with Fe2O3 and MnO2 Nanomaterials

Serpil Edebali
Abstract—Novel nanocomposite adsorbents for Cr(VI) removal from aqueous solution were synthesized by modifying perlite with α-MnO2 and γ-Fe2O3 nanoparticles. Nanocomposite adsorbents were characterized using Scanning Electron Microscopy (SEM) and FTIR. The adsorption capacity for Cr(VI) was found to be highly pH dependent and the adsorption kinetics followed the pseudo-second order kinetic model when compared to first-order kinetic model. The adsorption capacity was 8.64 and 7.6 mg g-1 for γ-Fe2O3 and α-MnO2 containing adsorbents as compared to very low adsorption capacity for perlite alone, confirming that these composites retain the constituent nanomaterial properties while being macroscopic particles suitable for chromium removal in water treatment.

Index Terms—Nanomaterials, Cr(VI), modification, perlite.
