Abstract:  The treatments of wastewaters contained dyestuffs are difficult and require special advanced treatment technologies. It is known that the adsorption is one of the effective methods commonly used for treatment of wastewaters. In this study, the removal of Rhodamine-B was studied by using modified clay as an adsorbent reagent. The effects of relevant parameters, namely; reaction time, adsorbent concentration, NaCl concentration and the pH have been investigated on the decolorization efficiency using central composite design. A model has been obtained among removal efficiency and relevant parameters. Then, the obtained model was optimized. The proposed method was applied successfully to remove Rhodamine-B in the real sample.
