چکیده
The corrosion inhibition of mild steel by 7-(ethylthiobenzimidazolyl) theophylline (7-ETBT) in 1 M HCl medium was investigated through weight loss and Tafel polarization techniques within a temperature range 298 to 318 K. efficiency depends on the concentration 7-ETBT reaction system temperature. maximum values 90.73 87.06 %, respectively, were estimated using both at results suggest spontaneous predominant physical adsorption metal surface which obeys Langmuir isotherm model. Furthermore, method revealed that is mixed-type inhibitor. Potentiodynamic are accordance with data good extent.
