[Fe（H2O）6]2+的光氧化在λ 6.5下进行< 300 nm with formation of a solvated electron. At pH >，然而，光化学由[Fe（OH）]+（aq）物种主导，其即使通过λ > 400 nm的过滤光也被光氧化为Fe III，而不形成溶剂化电子。即使在0.56 mol dm-3 NaCl存在下，γ-FeO（OH）也在整个范围内析出。pH值的机制上的影响进行了讨论，是CO2固定的影响。
Photo-oxidation of [Fe(H2O)6]2+ proceeds at λ < 300 nm with formation of a solvated electron. At pH > 6.5, however, the photochemistry is dominated by the species [Fe(OH)]+(aq), which is photo-oxidised to FeIII even by filtered light of λ > 400 nm, without formation of solvated electrons. The compound γ-FeO(OH) is precipitated throughout the range, even in the presence of 0.56 mol dm–3 NaCl. The effect of pH on the mechanism is discussed, as are the implications for CO2 fixation.
