“…The most widely used corrosive solutions contain HNO 3, HCl and H 2 SO 4 . So these medium have induced a great deal of research on copper corrosion [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] . The use of chemical inhibitors is one of the most practical methods for the protection against corrosion in acidic media.…”

The inhibition efficiency of various concentrations of phenylazo-2-naphthol on thecorrosion of copper in 1N aqua regia (HCl+HNO 3 ) was investigated by weight loss method at room temperature. The corrosion rate of copper and surface coverage of the inhibitor on the metal surface was also calculated from the weight loss data. The open circuit potential values of the system substantiate the corrosion behavior data. Langmuir adsorption isotherm concept was experimented to the adsorption behavior of inhibitor.
