We reveal that with the initial phase of iron reduction, ferrihydrite undergoes transformation to secondary phases and increases As (III) retention (relative to abiotic controls). However, with increased reaction time, cessation of the phase transitions and ensuing reductive dissolution result in prolonged release of As (III) to the aqueous phase.
