Adsorption studies of malachite green using activated carbonPrepared from jackfruit seeds

This project work focuses on study of adsorption of Malachite Green dye on jackfruit seed carbon. Inexpensive and environment friendly adsorbent is used for the removal of malachite green dye from aqueous solution. Studies were conducted to check the effect of different experimental parameters such as adsorbate dose, temperature, and initial concentration of malachite green, contact time, pH. The optimum conditions were evaluated from these parameters. The optimum conditions include contact time of 60 minutes, pH 5, temperature 30oC and 1gm adsorbate dosage. Study of adsorption isotherms was carried out at this optimum condition which gives us the best fitting adsorption isotherm model. The equilibrium data was fitted to Langmuir and Freundlich models and the results showed that the adsorption data agreed well to Freundlich isotherm than Langmuir isotherm. The results indicated that jackfruit seeds carbon can be used as an alternative adsorbent for treatment of effluents containing malachite green dye.
