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.

再生水中培养铁氧化菌对碳钢的腐蚀行为

采用静态挂片法、电化学分析、扫描电镜、电子能谱、红外光谱和x射线衍射等方法研究了再生水中铁氧化菌(IOB)对碳钢的腐蚀行为。结果表明:IOB通过附着在碳钢表面，加速了碳钢的腐蚀50 ~ 100%，有IOB体系的腐蚀电位(负23 ~ 36%)高于无IOB体系;在接种了IOB的中水中，碳钢表面细菌生长(形成生物膜)，钢板表面出现点蚀现象，而未接种IOB的中水未出现点蚀现象。无论是否存在IOB，腐蚀产物主要由FeOOH和CaCO3组成，但存在IOB时腐蚀产物更为复杂。

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.
