摘要：The effect of dithiolo[4,5-b][1,4]dithiepine(P1) dye on the electrochemical corrosion of mild steel in HCl solutions was studied using gravimetric techniques at 308K. The results indicate that dithiolo[4,5- b][1,4]dithiepine(P1) acts as an inhibitor in the acidic corrodent. The inhibition efficiency was observed to be sensitive to acid concentration and increased with an increase in (P1) concentration. The experimental data were corroborated with the Langmuir as well adsorption isotherms. The activation energy values of 40.70 kJ mol .1 calculated for the corrosion process in the absence and presence of (P1) suggest that the inhibitor molecules are chemisorption adsorbed on the mild steel surface.
