From: Arsenic removal performance and mechanism from water on iron hydroxide nanopetalines
(a) SEM micrograph of the iron hydroxide nanopetalines. EDX analyses of the iron hydroxide nanopetalines (b) and those after As(III) (c) and As(V) (d) adsorption. Initial As concentration was 75.0 mg/L, solution pH was 4.0, and adsorbent dose was 0.5 g/L.
