摘      要：This study describes the adsorption behavior of three arylthiophene derivatives namely:2-(4-amidino-3-fluorophenyl)-5-[4-methoxy phenyl] thiophene dihydrochloride salt(MA-1217),2-(4-amidinophenyl)-5-[4-chlorophenyll thiophene dihydrochloride salt(MA-1316) and 2-(4-amidino-3-fluorophenyl)-5-[4-ch lorophenyllthiophene dihydrochloride salt(MA-1312) at C-steel in 1.0 mol·L^(-1) HCl interface using experimental and theoretical *** and mass loss measurements showed that the inhibition efficiency(IE) of the arylthiophene derivatives increases with increasing concentrations and exhibited maximum efficiency 89% at 21×10^(-6) mol·L^(-1)(MA-1217) by mass loss *** investigated arylthiophene derivatives obey the Langmuir adsorption *** polarization studies the arylthiophene derivatives act as mixed-type *** analysis were carried out and *** mode of orientation and adsorption of inhibitor molecules on C-steel surface was studied using molecular dynamics(MD) *** chemical parameters as well as the radial distribution function indices and binding energies confirm the experimental results.
