摘要
利用原子力显微镜、电子探针和电化学测试等技术 ,研究了Ca2 + 离子对碳钢表面生物膜的形成、微生物腐蚀程度以及杀菌剂杀菌效果的影响 .结果表明 :Ca2 + 离子促进了硫酸盐还原菌 (SRB)的生长 ,增加了生物膜的致密性 ,降低了碳钢微生物腐蚀的敏感性 .但同时也增加了SRB对杀菌剂的敏感性 。
In this paper,the effect of Ca 2+ in the form of biofilm on the surface of carbon steel,the corrosion extent of MIC and the efficacy of bactericide were investigated via AFM,EPMA and EIS.The result shows that Ca 2+ can promote the growth of SRB,increase the compact of biofilm and decrease the sensitiveness of carbon metal to MIC.But at the same time Ca 2+ also decreases the sensitiveness of SRB to biocide which brings many difficulties to the prevention and cure of SRB.
