Steel has versatile application in chemical, structure and construction industries owing to its mechanical properties. However, it is susceptible to corrosion in acid environments. Thus, it requires to protect the steel from corrosion. Different types of corrosion resistance steel, coatings and inhibitors are developed to mitigate the corrosion, but, inhibitor is the best remedies to control the corrosion of steel in acid condition. Moreover, organic and green inhibitors used in acid condition for descaling, acid pickling, pipelines, boiler tubes and oil-wells. Organic inhibitors reduce the dissolution of steel in acid but, it is hazardous, expensive and needs expertise to synthesize the inhibitor. Therefore, there is utmost required to study and compile the latest research about the eco-friendly corrosion inhibitors, which showed more than 90% corrosion inhibition efficiency. In the present study, I have reviewed the state-of-arts, and compile the latest development in organic and eco-friendly corrosion inhibitor used in acid environment as well as suggested about the future scope and role of green inhibitor for sustainable society, which is economical, less hazardous and readily available from the natural sources.
由于其机械性能，钢铁在化学、结构和建筑等行业有广泛的应用。然而，它在酸性环境中容易腐蚀。因此，需要保护钢铁免受腐蚀。开发了不同类型的耐腐蚀性钢、涂料和抑制剂来减轻腐蚀，但抑制剂是控制酸性条件下钢铁腐蚀的最佳方法。此外，有机和绿色抑制剂用于酸性条件下的除垢、酸洗、管道、锅炉管和油井。有机抑制剂可减少钢铁在酸中的溶解，但它具有危害性、昂贵且需要专业知识来合成抑制剂。因此，非常需要研究和编译有关环保型腐蚀抑制剂的最新研究，这些抑制剂显示出超过 90%的腐蚀抑制效率。在本研究中，我回顾了现状，并编译了在酸性环境中使用的有机和环保型腐蚀抑制剂的最新发展，并就绿色抑制剂在可持续社会中的未来范围和作用提出了建议，绿色抑制剂在经济上更实惠、危害更小，并且可以从天然资源中获得。
