Abstract

Inhibition of copper corrosion in 0.1 mol.dm-3 Na2SO4 solution (pH 3) by two thiazole derivatives of 5(5'-methylfurfurylidene-2')-2,4-dioxotetrahydro-1,3-thiazole (MFDT) and 2-thiono-5-4'ethoxybenzylidene)-4-oxotetrahydro-1,3-thiazole (TEBOT) was studied by weight loss and potentiostatic polarization measurements. Inhibition efficiency follows the order: TEBOT > MFDT. The adsorption of each inhibitor on copper surface obeys Bockris-Swinkels adsorption isotherm (X =1). Kinetic and thermodynamic parameters of corrosion processes were calculated and discussed.
