Abstract:The yellow ochre-colored iron precipitates synthesized by two strains of different iron-oxidizing bacteria at different temperatures were analyzed by using ICP-AES, SEM, XRD and FTIR. The results indicate that both the precipitates produced by Leptospirillum ferriphium strain DY and Acidithiobacillus ferrooxidans strain GF are composed of jarosite and ammonium jarosite. However, the content of jarosite in the precipitates synthesized by strain GF is 5.53% higher than that synthesized by strain DY, but the content of ammonium jarosite in the precipitates synthesized by strain DY is 15.24% higher than that synthesized by strain GF.
Key words: jarosite; ammonium jarosite; Leptospirillum ferriphium strain DY; Acidithiobacillus ferrooxidans strain GF; precipitate
