Arsenic Precipitation in the Bioleaching of Realgar Using Acidithiobacillus ferrooxidans
Figure 4
FT-IR difference spectra of A. ferrooxidans BY-3. The FT-IR spectra were recorded using a FT-IR (NEXUS 670, Thermo Nicolet, USA) over the wave number range of 500 cm−1 to 4000 cm−1 under ambient conditions. a: Pristine: A. ferrooxidans BY-3 in the medium without realgar. b: As-loaded: A. ferrooxidans BY-3 in the medium with realgar.
