Corrosion inhibition of Copper in Nitric acid solutions by organic compound


The corrosion inhibition of copper by DES in 1MHNO3 has been investigated by Weight Loss (WL), Temperature effect and electrochemical techniques such as Potentiodynamic polarization studies were used. Results showed that DES has good inhibition efficiency on the corrosion of copper in1M HNO3 solution. Polarization measurement indicated that, the studied inhibitor act as a mixed type one. The inhibition efficiency depends on the concentration of inhibitor and reaches 99% at 30oc. The results obtained from the different methods are in good agreement. The SEM examination of the copper surface revealed that the compound prevented from corrosion by adsorption on its surfaces.
