dc.description.abstractAdsorption of 2-mercaptobenzothiazole (MBT) at copper surface has been studied to reduce the corrosion rateofcopperinHCl solution 0.5 M. The adsorption data were fitted into Langmuir, Freundlich and Temkin isotherms. The results showed three different values of adsorption isotherm, the R2 value of Langmuir isotherm model was the most linear, 0.9673. The maximum adsorption equilibrium constant of Langmuir isotherm model at copper surface was determined to be 2.33×105 L/molusing 50 ppm concentration of MBT at temperature 30 °C. Function of MBT at copper surface as corrosion inhibitor increases with the increase of inhibitor concentration. Analysis with ATR-IR spectrometry showed the adsorption type of MBTat copper surface aschemisorptions.en_US
