This study presents a novel akaganeite sorbent derived from waste bauxite residue (RMA) for the treatment of arsenic contaminated waters. The performance of the developed sorbent was compared against a commercial material (granular ferric hydroxide (GFH)) in order to contextualise the sorption c...detailed
In order to clarify the formation mechanism and conditions for akaganeite in long-term exposure, the influence of the former corrosion results on akaganeite formation was investigated by simulated experiments in laboratory. The combination of XRD, FTIR, SEM and EPMA enabled the identification of...detailed
Akaganeite, a Cl-bearing Fe(III) (hydr)oxide, has been recently discovered in Yellowknife Bay in Gale crater on Mars by the Mars Science Laboratory (MSL) Curiosity Rover. Akaganeite was associated with sulfate and sulfide minerals at Yellowknife Bay indicating that sulfate ions could be present ...detailed
