Abstract |
The main aim of this study is to utilize the response surface methodology for adsorption optimization of the Basic Red 46 dye using a novel adsorbent (functionalized multi-walled carbon nanotubes). According to the optimization model, the predicted value of the selected parameters for optimum conditions (maximum Basic Red 46 removal efficiency) were as follows: contact time= 76 min, initial pH= 9, adsorbent dose= 0.05 g/L and initial dye concentration= 105 mg/L. Under this condition, the dye removal efficiency was predicted to be 96.3%, which was relatively close to the experimental results (95%). Based on the analyses of variance results, the model presented a high R2 value of 95.12% for adsorption of the selected dye using multi-walled carbon nanotubes, which confirmed the model reliability.
