Synthesis and characterization of a new Azo dye and study of its adsorption mechanism on graphene oxide nanoparticles.

In this study, a novel azo dye was successfully synthesized, and its molecular structure was confirmed using comprehensive spectroscopic analyses. The adsorption performance of the dye onto graphene oxide (GO) nanoparticles was systematically investigated to evaluate its potential as an effective nano-adsorbent for pollutant removal. Thermodynamic analysis revealed that the adsorption process was exothermic, indicating stable interactions between the dye molecules and the graphene oxide surface. Kinetic modeling demonstrated that the adsorption behavior followed a pseudo-second model, suggesting that chemisorption is the dominant mechanism controlling the adsorption rate. Overall, the results highlight the promising applications of graphene oxide nanoparticles as effective materials for removing dyes and organic pollutants from aqueous environments.
