Abstract
Purpose: To show the effect of organic compounds containing O and N atoms on the corrosion inhibition of Cu in HNO3 and; the effect of some donating substituent groups on the corrosion inhibition.Design/methodology/approach: A range of published papers (1956‐1995), which aim to discuss the effect of organic compounds on the corrosion inhibition process. Two methods were used to determine the rate of corrosion, these methods were weight loss and polarisation. The effect of temperature and concentration were studied. The thermodynamic parameters for the process were computed and discussed.Findings: Provides information about weight loss and polarisation methods and how to prepare the Cu samples before and after tests. This will provide many academics relevant information before teaching or researching duties.Research limitation/implications: The paper may be using withdrawing substituting groups in addition to donating groups, this will improve the discussion, also the paper does not use the technique of impedance spectroscopy for comparison.Practical implications: To use Cu alloy for comparison and to use other compounds with larger molecular weights.Originality value: The use of some phthalimide derivatives as corrosion inhibitors for Cu in HNO3, provide more information on Cu corrosion for academic researchers and provide practical help for starting researchers.Keywords
