Abstract

The thermodynamics parameters and adsorption mechanism of the 2,2'-dithiobis(2,3-dihydro-1,3-benzothiazole), DDBT, as a corrosion retarder for Zn in 0.5 M HCl solution were studied by different techniques. Potentiodynamic polarization, thermometric and Gravimetric techinques, as well as, SEM surface investigations were employed. The data of different techniques were compatible and confirmed the inhibition effect of DDBT. The potentiodynamic polarization data disclosed that the DTDBT molecules behave as a mixed-kind inhibitor. The different thermodynamic parameters about the corrosion and adsorption processes were deduced to suggest the inhibition mechanism. The DDBT molecules are adsorbed on the C-steel surface confirming the Langmuir isotherm obeying a mixed mechanism (physical and chemisorption).
