摘要：

Clay mineral montmorillonite (Mt) magnetised by FexOy nanoparticles (NPs) was prepared by precipitation in two steps. Magnetically modified montmorillonite (MMt) was tested as a sorbent for the elimination of heavy metals ions from aqueous solutions. Zn(II), Cd(II), Pb(II) ions and their combination were successfully sorbed by magnetic composite (MMt). The equilibrium was achieved after 30 min of interaction of the liquid phase with MMt. The influence of solid-to-liquid ratio on the MMt sorption properties was studied as well. The amounts of ions removed by Mt and MMt were comparable. Therefore, magnetisation of Mt did not influence its sorption capacity. The composite can be easily removed by a magnetic field from the solution after sorption. (C) 2019 Elsevier Ltd.
