摘要：
The objective of this study was to optimize the removal of Novacron Blue 4R (NB4R) dye from aqueous solution by adsorption on activated carbon using response surface methodology, through Box-Behnken design. The effect of process parameters such as pH, initial dye concentration and adsorbent concentration was studied and optimal conditions of NB4R removal were defined. The results showed that the adsorbent concentration was the most important parameter that affects the dye removal efficiency (CR%). The best condition for predicted maximum NB4R removal was found to be at pH 7, initial dye concentration of 62.5 mg/L and adsorbent concentration of 15 g/L. In these conditions, predicted and experimental CR% were 96.24% and 93.63%, respectively. Adsorption using activated carbon was proved effective for textile dye removal.
