Paper Title
Optimization Of Basic Red 46 Adsorption From Aqueous Solutions By Functionalized Multi-Walled Carbon Nanotubes Using Response Surface Methodology

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. Keywords- Adsorption, Basic Red 46 (BR46), Functionalized Multi-walled Carbon Nanotubes, Response Surface Methodology.
