CWE/130/2017 当前世界环境 0973-4929 2320-8031 Enviro Research Publishers CWE--9-00 Removal of chromium Cr(VI) from waste water using a waste filter cake from sugar industry 1 Anna University, Department of Chemical Engineering, Alagappa College of Technology, Chennai, 600 025, India. 2008-12-31 10.12944 / CWE.3。2.08 Volume 3 Volume 3 257-260 Abstract

Sorption of Cr(VI) from an aqueous solution was studied using the filter cake obtained from the sugar industry at different pH (1 to 6) and initial chromium concentration (100 to 200 mg/L). From the result, it was observed that the percentage chromium removal was found to be decreased with increase in solution pH and the kinetic data fitted very well with the pseudo second order rate equation when compared to the pseudo first order rate equation. The equilibrium data was represented very well with the Freundlich isotherm model when compared to the Langmuir isotherm model.
