Abstract: Industrial Wastewater contains several type of dye, causing serious environmental hazard. The discharge of highly colored effluents into natural water bodies not only is aesthetically displeasing, but also impedes light penetration, thus upsetting biological processes within stream and thus required treatment before discharge into a water body. In the present study, Lima Beans Carbon, Musa Paradisiac Carbon converted into a low-cost adsorbent for the removal of Auramine Yellow from effluents of textile industry. Batch studies have been carried out to study the effect of pH, adsorbent doses, adsorbate concentration, temperature and contact time. The results of batch studies reveal that the adsorption of Auramine Yellow is strongly pH dependent and maximum Auramine Yellow removal is observed at equilibrium pH of 7.2. Optimum adsorbent dose and contact time are found to be 10 g/L and 360 minutes respectively. Kinetic studies have been performed to have an idea of the mechanistic aspects and to obtain the thermodynamic parameters of the process. The results also show that the adsorption decreases with increase in temperature, thereby showing the process exothermic in nature. Adsorption data have also been correlated with both Langmuir and Freundlich isotherm models.
