Modeling results of ferrihydrite dissolution kinetics with various oxalate/Fe ratios (blue, 0.1; green, 0.2; red, 0.5) under anaerobic and dark conditions respectively. Dash lines, short dot lines, solid lines and empty circle represent lager ferrihydrite aggregates, colloids of ferrihydrite, dissolved Fe and measured dissolved Fe, respectively.
