Abstract

Green Waste Material Chick-Pea husk, an agricultural waste product utilized for withdrawal of hexavalent chromium oxyanion from water. Chick-Pea husk surface area was analyzed by BET surface area analyzer. The further characterization of Chick-Pea husk was achieved by FT-IR spectroscopy, SEM and EDX analysis. Various parameters were investigated. Hexavalent chromium oxyanions were analyzed by U.V-Vis spectrophotometer. Desorption of hexavalent chromium oxyanions was successfully made by sodium hydroxide. The results obtained through various parameters are employed to explore Langmuir, Freundlich, D-R isotherms, adsorption-kinetics and thermodynamics of adsorption. The objective of this research is to eliminate toxic Cr (VI) oxyanions from polluted water. The technique successfully utilized to withdrawal hexavalent chromium oxyanions from water utilizing Chick-Pea husk by applying Batch mode.
