Nanocomposite Fe-Co-V/Zeolite: Highly Efficient Composite for Removal of Methyl Orange Dye

Abstract

Background: In recent years, the dye industry has rapidly been 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 a synthetic wastewater. Methods: After chemical synthesis of the nanocomposite, its structure was studied by spectroscopic techniques. The experiments were performed under different pH values (3-11), contact times (5-50 min), absorbent dose (0.5-0.6g), stirring speed (240-60 rpm), and different concentrations. Results: 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 the solution with a concentration of 20 mg/L at pH equal to 3, contact time 20 min, adsorbent dose 0.2 g, jar speed 180 rpm and temperature 25°C, which finally with the application of the optimal data, at a concentration of 2.5 mg/L, the best efficiency was obtained. The examination of isotherm diagrams and isotherm coefficients showed that the adsorption process follows the Freundlich equation. Conclusion: 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 air.

Modeling Strategies Based on Multiple Neural Network Systems Applied for a Monopolar and Bipolar Electrocoagulation

“…1 With distinct chemical properties, natural and synthetic dyes are chemical compounds recognized by their absorption of visible light within the electromagnetic spectrum, typically ranging from 400 to 700 nm. 2,3 In this context, it is estimated that approximately 60 to 70% of the dyes in use belong to the azo type, which carries a significant carcinogenic risk. Additionally, their resilience to typical biological degradation processes is heightened because of the presence of aromatic compounds and the electronwithdrawing nature of azo groups (-N=N-).…”
