Adsorption of Reactive Green and Reactive Red Dyes from the Aqueous Solution using Activated Carbons Arulanandam

Application of carbon developed from ground nut shell (GNC) and baby corn carbon (BCC) an agricultural waste product has been investigated for the removal of reactive green and reactive red dyes from aqua solution and waste water. Batch adsorption experiments were carried out for the removal of dyes RG and RR (reactive green and reactive red) from aqua solution on to GNC and BCC effect of important parameters initial concentrations of dyes, contact time, and dose variation was studied on removal of the dye. The removal increased from 93.75-94.91 % by decreasing the initial concentration 100 to 20mg/L. Equilibrium data were fitted to Langmuir and Freundlich isotherm constants were determined. The characterization of the physio chemically modified carbons was carried out. SEM and XRD analysis. UV-Visible and FT-IR analysis of before and after adsorption of dyes on the carbon surface area for morphological studies.
