The presence of toxic heavy metals such as chromium (VI) contaminants in aqueous streams, arising from the discharge of untreated metal containing effluents into water bodies is one of the most important environmental problems. Adsorption is one of the effective techniques for chromium (VI) removal from wastewater. Batch adsorption experiments were carried to fix the adsorption dosage and also to find the optimum pH. The equilibrium data satisfied both Langmuir and Freundlich isotherm models. The experimental data were analysed using the pseudo –second order kinetic model. The thermodynamic study has showed that the metal adsorption phenomenon onto AAVNS was favourable, endothermic and spontaneous.
