چکیده
|
The detailed study of 5-chloroisatin derivative against the corrosion of mild steel in a 1m h3po4 solution at 303 k was carried out using the method of weight loss measurements,tafel polarization techniques,electrochemical impedance spectroscopy (eis) and also scanning electron microscopy (sem). the results showed that the 5-chloro-1- (2- (dimethylamino) ethyl) indoline-2,3-dione (indo1) is a good inhibitor and its inhibition efficiency reached 91% at 10-3m. polarization measurements revealed that the 5-chloro-1- (2- (dimethylamino) ethyl) indoline-2,3-dione behaves as mixed-type. the adsorption of 5-chloro-1 (2(dimethylamino) ethyl) indoline-2,3-dione on a mild steel surface obeys the langmuir isotherm,has been studied at different temperatures. the kinetic parameters,and thermodynamic activations for the corrosion of mild steel,respectively,were calculated and discussed. © 2017,university of mohammed premier oujda morocco.
