Dyes removal from wastewater has been a matter of concern, both in the aesthetic sense and health point of view. Dyes removal from textile effluents on a continuous industrial scale has been given much attention in the last few years, not only because of its potential toxicity, but also mainly due to its visibility problem. There have been various promising techniques for the removal of dyes from wastewater. Economically feasible adsorbents of bio-origin with more adsorptive capacity are in demand for the removal of textile dyes from waste water. As the textile dyes are perilous to the environment, they should be removed from the industrial effluents before their disposal. Methylene blue dye is one of the most widely used in textile industries. Therefore we propose low cost adsorbents for the removal of Methylene blue dye. Present research mainly focuses on the removal of Methylene blue dye from aqueous solutions. A series of experiments were conducted in batch wise to estimate the effect of system variables on the amount of percentage removal of Methylene blue dye from the aqueous solution. The effects of variables such as contact time, initial concentration of Methylene blue dye in solution, amount of adsorbent dosage and temperature of the solution on the adsorption were studied. The adsorption data were well fitted by Freundlich isotherm model for neem leave and Langmuir isotherm model for Jatropha. Neem and Jatropha leave powder showed 89% and 98% removal of Methylene blue dye at the optimum operating conditions.
