Developing a green adsorbent to deal with Congo red dyes from wastewater was a significative exploration. In the work, we prepared an ionic liquid modified magnetic cellulose/sepiolite composite FSCS-cl-p(MBA-co-BVI) via a simple method, the process including the magnetic sepiolite/cellulose complex grafting the polymer of MBA and BVI. The high specific surface area of sepiolite and cellulose, the electropositivity of ionic liquids [Bvim][Br] and magnetic response of Fe3O4@SiO2 nanoparticles jointly promoted the adsorption performance of adsorbents. The composites were characterized by SEM, XR...
