摘要: Abstract Iron oxides and oxyhydroxides form via Fe3+ hydrolysis polymerization in many aqueous environments, but the pathway from monomers to oligomers then solid phase nuclei is unknown. In this work, using combined X-ray, UV–vis, Mossbauer spectroscopic approaches, we were able identify quantify long-time sought ferric speciation over time during oxyhydroxide formation partially-neutralized nitrate solutions ([Fe3+] = 0.2 M, 1.8
