Response Surface Modeling of Basic Blue 71 Removal from Aqueous Solution by N,O-Carboxymethyl-Chitosan

Abstract:

Abstract: N,O-carboxymethyl chitosans (N,O-CMC) were synthesized using water as a solvent. The structure of N,O-CMC is characterized by IR and XRD. N,O-CMC was used as adsorbent for the removal of basic blue 71 dye based on response surface methodology (RSM) from aqueous solution. A standard RSM design named central composite design (CCD) was employed for experimental design and analysis of the results. The combined effect of pH, contact time and temperature on the dye removal was studied and optimized using response surface modeling. The optimum pH, temperature and contact time for the process were found to be 8, 10 °C, 140 min, respectively, and the corresponding dye removal was 100%.
