Article Synopsis
- - The study investigates how arsenic (As(III)) impacts the oxidation rate of iron(II) (Fe(II)) and the types of iron (oxyhydr)oxides formed, particularly focusing on neutral pH conditions and varying As:Fe ratios.
- - Findings indicate that the presence of As(III) slows down the oxidation of Fe(II) and that the type of iron (oxyhydr)oxides formed changes with pH levels and As:Fe ratios, with specific minerals like lepidocrocite and goethite being inhibited at certain conditions.
- - Additionally, more than half of the As(III) is oxidized to As(V) at pH levels of 6.0
In this study, reductive dissolution of As(V)-ferrihydrite and the mobilization of As(V) in the presence of S(-II) were investigated under anoxic conditions. Mobilization of As(V) strongly depended on the S(-II):Fe ratio and the amount of As(V) loading on ferrihydrite. High S(-II):Fe ratio caused a more complete dissolution of ferrihydrite and a large fraction of As(V) could be released into solution.
