A novel adsorbent (FB-mZVI) was prepared, using tailings from iron ore concentration plants, fly ash and bentonite, to remove toxic crystal violet (CV) and methylene blue (MB) from water. The adsorbent was prepared as cylindrical-shape pellets to easily separate it from the water after the adsorption process. SEM Characterization revealed that the adsorbent was highly porous and constituted by Feo particles finely dispersed on an aluminosilicate matrix. The FB-mZVI adsorbent showed to have a superior adsorption capacity for CV and MB when compared to conventional adsorbents. Optimal synthesis parameters for the adsorbent synthesis are presented. In addition, adsorption mechanisms are proposed for the removal of CV and MB by the adsorbent.
