The best way to prevent corrosion of copper in acidic solutions is the use of organic inhibitors. The use of environmentally friendly inhibitors is important in the corrosion and inhibition of copper in environments with high chloride content. In this study, the inhibition effect of environmentally friendly (10(-2)-10(-4) M) 4-amino-N-(1,3)-thiazole-2-yl benzene sulfonamide was investigated to prevent corrosion of copper in 0.5 M HCl. The effect of the inhibitor on copper corrosion in acidic solutions was researched by cyclic voltammetry, Tafel polarization measurements and impedance measurements. In addition, the adsorption mechanism of 4-amino-N-(1,3)-thiazole-2-yl benzene sulfonamide on the metal surface was explained by Langmiur adsorption isotherm. In addition, SEM image of the surface of the copper plate, which was kept for 7 days with and without inhibitor, was taken. In addition, the time-dependent formation of hydrogen gas was measured. From the experimental results obtained, it was determined that 4-amino-N-(1,3)-thiazole-2-yl benzene sulfonamide at high concentrations inhibited copper corrosion by 84%.
