Alginate beads are well-known support materials in biosciences applications [1], and in the last years they are being used in the environmental field [2]. On the other hand, clays have been used in the last decades in the removal of toxic metals or organic pollutants from aqueous solutions due to favorable surface properties, availability, and environmental and economical considerations. The encapsulation of clays in alginate beads can lead to the generation of very practical and effective materials for the removal of pollutants.The aim of this work is to use alginate-clays beads materials to remove paraquat (PQ), a highly toxic herbicide used in Argentina.
