| English abstract | Cyanide is a very toxic compound that is released into the environment through industrial effluents; therefore, it needs to be removed prior to wastewater discharge. Adsorption is one of the most widely used treatment methods for removing contaminants from water and wastewater. In present research work response surface methodology was successfully employed for optimization and analysis of the adsorption process. Batch mode experiments were performed to determine the adsorption equilibrium of cyanide in aqueous solution. At optimum condition initial concentration (10 mg/l), contact time (1 h), adsorbent dose (1 g) and pH (8), 90.6% of cyanide adsorption was obtained. The factorial design and RSM analysis demonstrated that the experimental and the predicted values from the models were in agreement |
