Development and Testing of Antibacterial Materials for Sulfate-Reducing Bacteria
摘要
Sulfate-reducing bacteria (SRB) is one of the main microorganisms that induce MIC. In order to explore the influence of different SRB content in different water media on X65 test tablets, the corrosion mechanism and the effect of developed antibacterial materials were revealed from the electrochemical level. In this paper, the systematic simulation of seawater and production water was carried out, and fluorescence analysis, electrochemical analysis and scanning electron microscopy analysis were carried out. The study of electrochemical corrosion law shows that the corrosion current density under bacterial condition is significantly higher than that under sterile condition, indicating that bacteria promote corrosion. The plant-based Ag/Cu bimetallic nanoparticle inhibitor can inhibit the corrosion of carbon steel by sulfate-reducing bacteria.
