heal.abstract The dissolution of pure iron oxides by organic acids has been extensively reviewed. The mechanism of dissolution comprises three distinct steps: (1) adsorption of organic ligands on the iron oxide surface; (2) non-reductive dissolution; and (3) reductive dissolution. Reductive dissolution involves two stages: an induction period and an autocatalytic period. The overall dissolution process is affected by the pH of the initial solution, temperature, the exposure of solution to UV radiation and the addition of bivalent iron in the initial solution. en
