Nanocomposite Fe-Co-V /Zeolite: Highly efficient composite for removal of methyl orange dye

In recent years, the dye industry has been rapidly developed. Dyes are one in all the foremost dangerous groups of chemical compounds found in industrial effluents, which are of considerable importance for reasons like reduced light permeability and therefore the subsequent disruption of the method of photosynthesis in water sources. This study was performed to remove dye using Fe-Co-V /Zeolite from synthetic wastewater. 

After chemical synthesis of the nanocomposite, its structure by spectroscopic techniques was studied. Experiments were performed Under different pH conditions (3-11), contact time (5-50 minutes), absorbent dose (0.5-0.6 g), stirring speed (240-60 rpm), and different concentrations.

The results showed that the optimal and final conditions affecting the removal of methyl orange dye in the most suitable conditions for 200 mL of solution with a concentration of 20 mg/L at pH equal to 3, contact time 20 Minute, adsorbent weight 0.2 g, jar speed 180 rpm and temperature 25 °C, which finally with the application of optimal data, at a concentration of 2.5 mg/L, the best efficiency was obtained. Examination of isotherm diagrams and isotherm coefficients showed that the adsorption process follows the Freundlich equation.

According to the obtained results and physical and chemical properties of the synthesized nanocomposite, it can be used to remove pollutants from the environment such as wastewater and gaseous pollutants from the air.
