Treatment of Wastewater Containing Cr by Fe-Ti Modified Bentonite

Sun Ling

Abstract

Modified bentonite was characterized and studied with XRD,IR,SEM and XPS analysis.Factors such as dosage of adsorption agent,pH value and stirring time that affect Cr removal efficiency were examined,and results showed that the removal efficiency of Cr on Fe-Ti modified bentonite at optimised conditions reached 99%,with the residual concentration of Cr lower than national discharge criteria.
