Adsorption Behaviours of Anionic Azo Dye (Congo Red) from Aqueous Solution on Magnetic Expanded Graphite Material (EG@CoFe2O4) Composites

In this paper, a potentiality of magnetic expanded graphite material (EG@CoFe2O4) for the adsorptive removal of Congo red, an anionic azo dye, from aqueous solution was studied. The experiments were carried out in batch mode in which various experimental conditions including contact time, initial dye concentration, adsorbent dosage and pH were varied and their influences on the adsorption yield were investigated. The surface of the adsorbent...
