The control of mild steel corrosion is of technical, economic, environmental and aesthetic importance. One of the best options is to use inhibitors to protect mild steel from corrosion. Some organic corrosion inhibitors are toxic to the environment, as they are degradable but have the advantage of not containing heavy metals. The toxicity of some o...
