Cr(<scp>vi</scp>) removal by mesoporous FeOOH polymorphs: performance and mechanism

Abstract

The mesoporous FeOOH polymorphs, <italic>i.e.</italic>, goethite (α-FeOOH), akaganeite (β-FeOOH), lepidocrocite (γ-FeOOH), and feroxyhyte (δ-FeOOH) were synthesized and characterized before and after reaction with Cr(<sc>vi</sc>) using various analytical techniques.
