Abstract—In this study, an adsorbent (FO-Dowex) was prepared by modification of commercial strong base anion exchange resin (Dowex marathon MSA) with ferric oxide (FO) and applied as adsorbent for removal of As(V) from aqueous solution. The effects of initial iron concentration and reaction contact time on adsorption capacity of As(V) were investigated for optimal conditions of adsorbent. In addition, the FO-Dowex was characterized using scanning electron microscopy and Fourier transformed infrared spectroscopy. It was shown that the optimal initial iron concentration and reaction contact time were 0.5 mol/L and 12 h, respectively. Comparison of adsorption performance between the prepared FO-Dowex and the anion resin revealed that FO-Dowex exhibited higher adsorption capacity with the value of 74.07 mg/g compared to the one from anion resin (49.75 mg/g) under the same conditions. It can be suggested that the modification of anion resin with ferric oxide can significantly improve the adsorption performance in As(V) removal.

Index Terms—Adsorption, arsenic, ferric oxide, anion exchange resin.
