Sorption of Basic Dye (Rhodamine B) by Nano Porous Activated Carbon From Sterculia QuadrifidaShell Waste

The adsorption of Rhodamine B (Basic dye) on Sterculia quadrifida Shell Waste carbon was investigated to assess the possible use of this adsorbent for the processing of dyeing industry wastewater. The i nfluence of various factors such as initial dye concentration, agitation time and temperature on the adsorption capacity has been studied. The percentage removal of dye is observed to decrease with the increase in initial dye concentration. With increase in temperature the adsorption of dye also increases, indicating endothe rmic nature of the reaction. Adsorption isothermal data could be interpreted by the Langmuir and Freundli ch equations. Kinetic data have been studied using Elovich and Pseudo-second order equations for understanding the reaction mechanism.
