Benzotriazole Copper Inhibition Tetra-n-butylammonium bromide
|
|
Résumé :
|
The corrosion inhibition behavior of benzotriazole (BTA) on copper in 17 wt% tetra-n-butylammonium bromide (TBAB) aerated aqueous solution was investigated by weight-loss tests, potentiodynamic polarization, electrochemical impedance spectroscopy, and scanning electron microscopy/energy dispersive X-ray spectroscopy. BTA is a good inhibitor in 17 wt% TBAB solution. The inhibition efficiency of BTA increases with increasing inhibitor concentration, attaining efficiencies of up to 90% calculated according to different methodologies. Adsorption of BTA in 17 wt% TBAB solution on the copper surface was found to obey the Langmuir adsorption isotherm.
