[Biosynthetic schwertmannite as catalyst in Fenton-like reactions for degradation of methyl orange].

Biosynthesized schwertmannite was used as catalyst in photo-Fenton-like reaction to facilitate the degradation of methyl orange (MO). Schwertmannite was synthesized through the oxidation of FeSO4 by Acidithiobacillus ferrooxidans LX5 cell suspension at an initial pH 2.5 and 28 degress C for 3 days and characterized using X-ray diffraction spectroscopy and scanning electron microscope.
