In this review article, illustrating the impact and fundamental stuff of microbially influenced corrosion (MIC) along with mechanism, maintenance of materials, human life, wellbeing and inhibitors for cooling towers. Corrosion is a natural mechanism of oxidation and reduction of metal ions by chemical and electrochemical processes and microorganism accumulation. MIC occurs through the aggregation of microbes which can be secreting the extra polymeric substances (EPS) that oxidation of the metal surface. According to the reviews, in the cooling water system, the corrosion begins in the anode charge because its oxidation reaction quickly takes place on the metal surface than the cathode charge. Annihilate the corrosion process needs certain helper substances such as chemical or green compounds, called inhibitors. Corrosion inhibitors typically adopt the adsorption mechanism due to the presence of organic hetero atoms. Chemical and green inhibitors are used to prevent corrosion processes and since ancient times, vast quantities of chemical inhibitors have been used in industry due to their effectiveness and consistency. But still, the chemical inhibitors are more toxic to humans and the environment. Instead of chemical inhibitors, green inhibitors (natural products like plant leaves, flowers, stem, buds, roots and sea algae) are developed and used in industries. Generally, green inhibitors contain natural compounds, high inhibition efficiency, economic, eco- and human-friendly, and strong potential features against corrosion. Thus, a lot of research is ongoing to discover the green inhibitors in various parts of plants and seaweeds.

废水循环利用对微生物影响的加工业腐蚀及其控制措施-综述

在这篇综述文章中,说明了微生物影响的腐蚀(MIC)的影响和基本成分,以及机理,材料维护,人类生活,福祉和冷却塔抑制剂。腐蚀是通过化学和电化学过程以及微生物积累而氧化和还原金属离子的自然机制。MIC是通过微生物的聚集而发生的,这些微生物可以分泌出金属表面氧化的多余聚合物(EPS)。根据评论,在冷却水系统中,腐蚀始于阳极装料,因为其氧化反应比阴极装料在金属表面上迅速发生。消除腐蚀过程需要某些辅助物质,例如化学或绿色化合物,称为缓蚀剂。由于存在有机杂原子,缓蚀剂通常采用吸附机理。化学抑制剂和绿色抑制剂用于防止腐蚀过程,并且自古以来,由于其有效性和一致性,在工业中已使用了大量化学抑制剂。但是,化学抑制剂对人类和环境的毒性更大。开发了绿色抑制剂(植物叶,花,茎,芽,根和海藻等天然产物)来代替化学抑制剂,并将其用于工业中。通常,绿色抑制剂包含天然化合物,高抑制效率,经济,生态和人类友好性以及强大的抗腐蚀潜能。因此,正在进行大量研究以发现植物和海藻各部分中的绿色抑制剂。
