... it is resistant to many chemicals and atmosphere (Antonijevic and Petrovic, 2008). For the protection of metals against the destructive attack in acidic environments, the use of inhibitors is one of the most practical methods. Various parts of plant materials such as leaves, seeds or bark extracts are of interest...

... Sulphuric acid Plants Mild steel has numerous applications in industrial installations and equipments. However, the metal is often prone to attack by corrosion especially in acidic or alkali medium hence inhibitors must be used if the life span of this valuable metal must be guaranteed (Arab...

... Plants The use of corrosion inhibitors for the protection of mild steel in industries has been widely investigated. Most corrosion inhibitors are organic compounds having heteroatoms in their aromatic system (Eddy and Odoemelam, 2009 ; Odoemelam and Eddy, 2008). Some of these compounds have been...
