EVALUATION OF BIOMASS, INDIAN JUJUBA SEED (IJS) FOR REMOVAL OF CONGO RED

The present investigation deals with the removal of Congo Red (CR) from aqueous solution by using Indian Jujuba Seed (IJS) as low-cost biosorbent. The effect of pH and size experimental parameters has been investigated using a Batch adsorption technique. Adsorption data were modeled using Langmuir and Freundlich adsorption isotherms. Adsorption kinetics was verified by pseudo-first order, pseudo-second order and intraparticle diffusion models. The kinetic adsorption data fitted the pseudo-second order kinetic model well and also followed the intraparticle diffusion model. The results indicated that IJS could be employed as low-cost biosorbent in wastewater treatment for the removal of CR.
