Abstract
The corrosion behaviors of carbon steel in the presence of iron oxidizingbacteria (IOB) in reclaimed water was investigated mainly using the static hanging piecemethod, electrochemical analysis, SEM, EDAX, FT-IR and XRD. The results showedthat IOB accelerated the corrosion of carbon steel by 50–100% by attaching to its surface;the corrosion potential of the system with IOB was higher (23–36% negative) thanthat without IOB; bacteria grew (biofilm formed) on the surface of carbon steel and pittingcorrosion occurred on the coupons in the reclaimed water inoculated with IOB, whileno pitting corrosion occurred in the system without IOB. The corrosion products mainlyconsisted of FeOOH and CaCO3 whether IOB existed or not but were more complicatedin the presence of IOB.
期刊介绍：
The international Journal of Residuals Science & Technology (JRST) is a blind-refereed quarterly devoted to conscientious analysis and commentary regarding significant environmental sciences-oriented research and technical management of residuals in the environment. The journal provides a forum for scientific investigations addressing contamination within environmental media of air, water, soil, and biota and also offers studies exploring source, fate, transport, and ecological effects of environmental contamination.
