Abstract
In this work, Zeolite/Fe3O4 nanocomposite used for adsorption of Blue 41 cationic dye from aqueous solutions in a wide range of concentrations. Analyzes of FTIR, XRD, FESEM, VSM and XRF have confirmed the nature and the structure of Zeolite/Fe3O4 nanocomposite adsorbent. The obtained results and analyzes determined that adsorption process efficiency increases by increasing reaction time, pH and amount of adsorbent and versus, increasing dye initial concentration causes significant decrease of adsorption efficiency. The obtained results of adsorption of isotherm and kinetics study illustrated that data follows Freundlich model and pseudo second order kinetics. Under optimum conditions of pH = 9, dye initial concentration of 100 mg/L, adsorbent dose of 3 g/L and reaction time of 60 min, removal efficiency was obtained 71.4 %. Totally results showed that Zeolite/Fe3O4 nanocomposite can be used by scrutiny of operating conditions of the adsorption process as a adsorbent with high effectiveness and availability, eco-friendly and cost-effective in order to removing dye from waste water of different industries.
Highlights
In this work, Zeolite/Fe3O4 nanocomposite used for adsorption of Blue 41 cationic dye from aqueous solutions in a wide range of concentrations
The resultant spectrum of FTIR was used before adsorption process of Blue 41 cationic dye to determine vibratory frequency changes in functional groups
It can be conducted that the maximum adsorption capacity of Blue 41 cationic dye on Zeolite/Fe3O4 nanocomposite, which has obtained in this study by the other adsorbents that have been tested, is better
Summary
Blue 41 cationic dye used in this research was made by Alvan Sabet Hamedan. The general specification of dye is presented in (table 1) [13]. H2SO4 and NaOH 0.1 M were used to set out the pH of the solution containing dye. All substances used in experiments were prepared from Germany, Merck Company, with laboratorial degree of purity. It should be noted that at all stages of experiments, double distillated water was used
