Despite being banned in several countries due to its high toxicity, the herbicide paraquat is still widely applied, putting water resources at risk of contamination. In this work, we use, for the first time, magnetic nanosorbents functionalized with biopolymers for the efficient remediation of water contaminated with paraquat. Besides the high adsorption capacity, the clean up was easily achieved with a magnetic gradient and the particles were recycled for at least three cycles with removal over 95%.
