Abstract

Introduction: Today, contamination of surface and underground water sources with textile dyes is one of the most serious environmental problems facing humans. Nanocomposites are a new generation of superabsorbents that have been proposed by many researchers as a promising strategy to reduce water pollution. In this study, a Ceramic Carbon Nanocomposite containing multi-wall carbon nanotubes was synthesized and used as an adsorbent for removal of anionic acid red 37 from aqueous. Methods: This experimental study was carried out at the laboratory level. The statistical population included synthetic aqueous solutions of acidic red dye 37 containing different amounts of synthesized nanocomposite. In absorption experiments, the effect of different factors such as pH, contact time, initial concentration of the dye, and the amount of Ceramic Carbon Nanocomposite on the color absorption from solution was investigated. The Adsorption conditions were optimized by response surface method. In addition, we investigated the dye absorption on ceramic carbon adsorbent based on Langmuir and Freundlich models. Results: The optimal conditions were obtained at pH =4. 2, contact time = 90 min, initial concentration of 24 mg / L, and 1. 6g of Ceramic Carbon Nanocomposite. In this condition, the maximum absorption efficiency of 97 percent was obtained. The maximum absorption capacity of the proposed nanocomposite was determined as 45. 6 mg / g, which is comparable to similar carbon absorptions. Conclusion: Based on the results, we found that the best model for justifying the dye absorption behavior on composite is the Freundlich model and the pseudo-second order equation can be used to study the Kinetic behavior of AR37 absorption.
