From: Arsenic removal performance and mechanism from water on iron hydroxide nanopetalines
(a) Influence of solution pH on the removal of As(V) and As(III) with initial As concentrations at 75 mg/L and dosage of 0.5 g/L. Effect of competitive anions on As(V) (b) and As(III) (c) removal at pH 7.0 with initial As concentrations at 75 mg/L and dosage of 0.5 g/L. (d) Reusability of iron hydroxide nanopetalines on the removal of As(V) and As(III) with initial As concentrations at 75 mg/L and dosage of 0.5 g/L.
