Abstract:

Background: In this study, cysteine-coated magnetite nanoparticles (F3O₄@Cys MNPs) were synthesized by chemical method and applied as a recoverable and efficient adsorbent for the removal of carmoisine dye from aqueous solutions. The synthesized MNPs were characterized by FT-IR, XRD, SEM, and TEM studies.

Methods: The effect of various experimental parameters on the dye removal efficiency was studied using Taguchi orthogonal array design (L₁₆ array). Under the optimum conditions (pH = 2, stirring time = 30 min, adsorbent amount = 0.1 g and without salt addition), more than 92% of carmoisine was removed from the aqueous solutions.

Results: The kinetic studies showed rapid adsorption dynamics by a pseudo second-order kinetic model, confirming that diffusion controls the adsorption process. Dye adsorption equilibrium data were fitted well to the Freundlich isotherm, and the synthesized adsorbent showed high removal efficiency.

Conclusion: The obtained results showed that the synthesized MNPs act as a reusable adsorbent for carmoisine removal with an easy procedure.
