Abstract
Akaganeite (βFeOOH) occludes chloride within its crystal structure and adsorbs it onto it surface during its formation. βFeOOH was synthesised by solid-state and aqueous precipitation routes. The amount of adsorbed chloride removed by a single aqueous wash was measured. The impact of the synthesised βFeOOH on the oxidation rate of iron was determined by using a remote oxygen sensing technique to record oxygen concentrations within a sealed vessel, internally controlled to 80% relative humidity and containing mixture of βFeOOH and iron powder. The oxidation rate of iron was directly related to the mass% of adsorbed chloride removed by the aqueous wash. This contributes to understanding of both iron corrosion and the development of conservation treatments.
