Abstract

The adsorption of Rhodamine B (Basic dye) on Leucaena leucocephala seed shell waste carbon was investigated to assess the possible use of this adsorbent for the processing of dyeing industry wastewater. The influence 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 endothermic nature of the reaction. Adsorption isothermal data could be interpreted by the Langmuir and Freundlich equations. Kinetic data have been studied using Elovich and Pseudo-second order equations for understanding the reaction mechanism.
