7. Appendix
This research work involved the use of low cost and easily available biomass, powdered leaves of Azadirachta indica for removal red 120dye from water. Studied operating variables include pH, initial dye concentration, equilibrium and kjinetics. Rate of absorption was maximum at 2pH and Equilibrium experimental data was scrutinized using Langmuir, Freunlich and tempkin adsorption isotherms. Results were favorable for all three isotherms but tempkin gave comparatively best fit to equilibrium experimental data. Adsorption kinetics was found to obey pseudo second order kinetics model. Purpose of this work was to show that adsorption of reactive red 120 dye onto the plant biomass is one of the efficient and lowest cost method for removal of dyes as compared to other conventional methods.
