The increasing use of pesticides in agriculture, environmental pollution became an imminent problem in modern society. Reusable materials as a sustainable technology has a broad application prospect in water treatment, and magnetic graphene materials are proposed in this study. Magnetic manganese ferrite nanoparticles have been successfully synthesized on graphene. It was reported 89% of glyphosate removal from aqueous solution after 6 h of contact time. The adsorbent showed to be a reusable adsorbent, as it could be reasonable regenerated with 0.1 M NaOH solution, obtaining removals higher than 80% after regeneration. The results showed that MnFe2O4-G might be used as an alternative adsorbent for water treatment contaminated with glyphosate.
