Adsorption of As (V) and As (III) from aqueous solution by lepidocrocite (γ-FeOOH) nanoparticle
γ-FeOOH nanorods an adsorbent for As(V) and As(III) removal was prepared by a chemical co-precipitation method. The maximum adsorption capacities at pH6 for As(V) and As(III) were 63.75 and 88.99 mg/g, respectively, higher than those of Fe2O3, Fe3O4... The adsorption data accorded with Freundlich is...
