Expired drugs as corrosion inhibitors for metals and alloysAuthor(s): R.S.Abdel Hameed
Due to the high cost and the toxicity of widely used corrosion inhibitors and the ever-tightening environmental regulations surrounding their use and disposal, there is great interest in replacing harmful inhibitors with effective non-hazardous alternatives. Over the past two decades, extensive research and development have led to the discovery of new classes of corrosion inhibitors, and the importance on the use of several drugs as corrosion inhibitors has grown. There are great efforts to use drugs as corrosion inhibitors for metals, but the use of the expired drugs as corrosion inhibitors for metals is limited. The present review reports the new trends aimed to recycling of expired drugs and using it as corrosion inhibitors for metals in different corrosive media.
