Adsorption Behavior and Corrosion Inhibition of 2-Benzothiazolethiol for Q235 Steel in Hydrochloric Acid Solution

Abstract:

The weight loss measurements and potentiodynamic polarization techniques are used to assess the inhibitive and adsorption behaviour of 2-Benzothiazolethiol (BTT) for Q235 steel in hydrochloric acid solution. The inhibition efficiency is found to increase with increase in BTT concentration but decrease with rise in temperature and hydrochloric acid concentration. The results show that BTT acts as a good corrosion inhibitor in hydrochloric acid solution. Adsorption of BTT is found to obey Langmuir isotherm. Polarization curves indicate BTT is a mixed-type inhibitor.
