“Chitosan/Montmorillonite” Nanocomposites: Adsorption of Cr(III)

The interaction between Cr(III) and “chitosan/montmorillonite” nanocomposites has been studied. Also, the adsorption kinetic of chromium in prepared chromium solution and in tannery waste-water has been presented. The article confirmed the initial interest in using “chitosan/montmorillonite” nanocomposites as depolluting agent, especially MMTCTf2% nanocomposite exhibits the best adsorption capacity of Cr(III) as compared to MMTCTf1% and MMTCTf3%. According to ICP-OES analysis MMCTf2% can adsorb 45% of Cr(III) from this effluent.
