Enhanced removal of fluoride and arsenate ions from aqueous solution by magnetic Mg–Al composite oxides (Fe₃O₄@Mg–Al–O)

Herein, magnetic Mg–Al composite oxides (Fe3O4@Mg–Al–O) as an effective adsorbent were successfully prepared. And the magnetic Fe3O4 microspheres could improve the separability and removal ability, which were loaded onto the surface of Mg–Al–O. The adsorption behaviors of Fe3O4@Mg–Al–O for fluoride (F−) and arsenate ions [As (V)] were studied by static adsorption experiments, such as initial pH, contact time, co-existing ions, and so on. The...
