| 摘 要： | 利用原子力显微镜、电子探针和扫描电子显微镜等测试方法研究了培养基介质中双季铵盐化合物MDOPD对腐生菌(TGB)的抑制机理．研究结果表明：MDOPD能够在培养基中的碳钢金属表面优先吸附，形成完整致密的有机吸附膜，使细菌新陈代谢产物难以到达金属基体表面；同时，MDOPD使生物膜的沉积变得疏松，氧浓差腐蚀和膜下硫酸盐还原菌引起的腐蚀都受到有效的抑制．

| Abstract: | AFM (Atom Force Microscopy), EPMA (Electronic Probe Measurement Analysis) and SEM (Scanning Electronic Microscopy) were used to study the mechanism of bisquats named MDOPD( N Metronidazole N (Dodecane) 3 Oxal 1,5 Pentanedilamonium Dichloride) against Total Growth Bacteria in the culture medium. The experiment results showed that MDOPD could form an integrated and compact absorption film on Q235 steel coupon in the culture medium, and it is difficult for the metabolism production by TGB to deposit on the surface of carbon steel. At the same time, the corrosion caused by difference of oxygen concentration or Sulfate Reducing Bacteria under the loose biofilm would be effectively restrained. |
