Sugarcane bagasse treated with hydrous ferric oxide as a potential adsorbent for the removal of As(V) from aqueous solutions

► Modification of sugarcane bagasse with iron oxyhydroxide (SCB-HFO) was realised. ► The number of functional groups on the (SCB-HFO) increased with modification. ► Modified FH is an efficient adsorbent for eliminating As(V) from polluted water. ► The sorption yield reached maximum value as 98% at pH 4 for As(V) ions. ► The sorption capacity of (SCB-HFO) was 22.1 mg/g.
