In the world, water pollution is one of the most important problems. For this purpose, it is necessary that waste water must be treatment before discharge to the environment. It is known that adsorption is the well process for treatment of pollutant in an aqueous environment. In this study, the removal of Malachite green (MG) from aqueous solution using pulp (Nigella sativa) was investigated. Effects of pH, initial dye concentration and time on adsorption of MG were studied in a batch system. The available data were applied to Langmuir and Freundlich isotherms. The Langmuir model is the best fitted (R2=0.999) for the adsorption of MG from using pulp (Nigella sativa). Moreover, kinetic of adsorption were also calculated. The interaction between the pulp surface area and the dye was determined by scanning electron microscopy. The study emphasized that the Nigella sativa pulp is a no-cost and powerful adsorbent for the removal of MG.
