ABSTRACT

 

Studies in corrosion behavior of mild steel in aqueous hydrochloric acid solutions were carried out using conventional weight loss and thermometric techniques in presence of various dyestuffs Inhibitive power of dyestuff understand with special reference to Reaction number, temperature difference (T max) etc. The plot of inhibitors concentrations log (c) Vs. Log [ 6)39 / 1-6)39 ] suggest that all these inhibitors obey Langmuir adsorption isotherm equation. Percentage. Inhibition efficiency determines from the results of conventional weight loss and thermometric technique can be satisfactorily used to evaluate various dyestuffs as corrosion inhibitors for mild steel in aqueous hydrochloric acid solution.

 

Keywords : Corrosion, Dyestuffs, Thes mometris Electrochemical, Reaction number.
