摘要	Hydrous manganite (MnOOH) nanorods were synthesized by a simple precipitation process in ethanol at room temperature, which eliminated high temperature calcination or a hydrothermal process in the creation of most manganese oxide-based adsorbents and resulted in low energy consumption and subsequently low production cost. These MnOOH nanorods had a high specific surface area at similar to 165.9 m(2) g(-1) and their total pore volume was similar to 0.561 cm(3) g(-1), which was beneficial to their arsenic removal performance. These MnOOH nanorods demonstrated a superior As(III) removal performance from an aqueous environment. At near neutral conditions (pH similar to 7), their arsenic adsorption capacity was over 431.2 mg g(-1), which was among the highest reported values in the literature. The superior As(III) removal performance of these MnOOH nanorods relied on the adsorption and subsequent oxidation of As(III) to less mobilized/toxic As(V), and its fixation on their surface to form inner-sphere arsenic surface complexes.
