Core-shell magnetic zeolite particles from red mud

Abstract

Zeolites are microporous, aluminosilicate minerals extensively used in industry. An interesting feature about these materials is their good performance as ion exchangers, which allows the capture of metal cations considered toxic and harmful, for example. In this work, magnetic zeolites from LTA group were prepared using the magnetic particles found in the red mud resulting in a core-shell system. The perspective is to apply the obtained composites in water treatment and to be able to remove them taking advantage of their magnetic behavior.
