Chromium(VI) Removal Using Biosorbents Derived from Moringa Oleifera

S Sasikala and G Muthuraman

The increasing influx of heavy metals into water bodies from industrial and domestic activities is of the global concern because of their well-documented negative effects on human and ecosystem health. Moringa oleifera is low cost and environmental friendly material to remove the Cr(VI) from aqueous solution. This study is carried out with the objectives to optimize the feasibility condition of contact time, biosorbents dosage and pH range in removing Cr(VI) by using Moringa oleifera seed powder. The removal characteristics of Cr(VI) by Moringa oleifera was analyzed using UV-Visible spectrophotometer. The optimum percentage removal of Chromium achieved at 120 min at pH 5. The initial metal ion concentration and effect of temperature, Freundlich and Langmuir adsorption isotherm model and kinetics were studied.
