摘要：

The inhibitor effect of 3,5-diphenyl-4H-1,2,4-triazole (DHT) on the corrosion of mild steel in hydrochloric acid solution was investigated at 30 degrees C using electrochemical and weight loss measurements. Polarisation curves revealed that this organic compound act as mixed-type inhibitor and inhibition efficiencies up to 98% can be obtained. The inhibition efficiency calculated from these techniques an in reasonably good agreement. X-ray photoelectron spectroscopy (XPS) spectra of the steel surface treated with the 1 M HCl solution containing the DHT molecules revealed their adsorption on the surface. The DHT appears to function through the general adsorption mode following the Langmuir adsorption isotherm model. (C) 2000 Elsevier Science B.V. All rights reserved.
