Abstract:

This study was aimed to use Cellulose dusts (CD) produced in drying section of paper mills of paper making industry as apotential adsorbent to remove methylene blue (MB) dye from aqueous solution. The adsorbent was characterized byscanning electron microscopy and Fourier transform infrared spectrometer and X-ray Diffraction. The influences of theeffective parameters including pH solution, adsorbent dosage, initial MB concentration, and contact time were optimizedby CCD which stands for central composite design. The influence of these parameters on the adsorption capacity wasanalyzed using the batch process. The accuracy of the equation that is produced by CCD was affirmed by the varianceanalysis and also by calculating the correlation coefficient that connects the predicted and the empirical values of thepercentage of removed MB dye. Maximum removal percentage of MB dye (98.05 %) which obtained at pH 9.84, adsorbentdosage 4.38 g L-1, MB concentration 75.50 g L-1 and time 208.13 min. Freundlich, Temkin, Harkins-Jura and Langmuirisotherms are used to analyze the empirical data. Results revealed that the data is in a satisfying agreement with theFreundlich isotherm (R2= 0.99). Pseudo-first order, Pseudo-second-order, Elovich and Intraparticle diffusion models wereused to fit the kinetic data and it is found out that MB dye’s adsorption onto CD has a good agreement with the pseudosecond-order kinetic model. The results showed that CD can be an efficient and low-cost adsorbent for methylene blueadsorption.
