Abstract:
Iron(III)‐entrapped γ‐alumina nanosorbents were prepared by an environmentally benign method using an ionothermal process based on an ionic liquid to synthesize the γ‐alumina host and a sonochemical method to entrap the iron(III) guest. The morphology of the alumina depends on the aluminum precursor used, giving aligned bundled and randomly debundled γ‐alumina nanorods as well as wormlike mesoporous alumina. In particular, the rodlike structure shows significantly greater mesoporosity than the wormlike porous γ‐alumina structure. Moreover, entrapment of iron(III) in the γ‐alumina nanosorbents with randomly debundled rodlike structures leads to the greatest As V removal capacity and the fastest adsorption rate as compared to the other Fe III ‐entrapped adsorbents, as a result of its larger surface area and pore sizes. Thus, this method provides a clean and effective route to an advanced host–guest adsorbent system for application in the removal of arsenic from drinking water.
