| Abstract: | The rates of anodic corrosion of copper
plates in different concentrations of phosphoric acid (6, 8, 10, 12 and 14 mol)
have been studied by measuring the limiting current of anodic dissolution. The
rates of corrosion are measured in absence and presence of aniline derivatives,
such as aniline, p-bromoaniline, m-chlororaniline, o-chlororaniline,
p-chlororaniline and p-methyl
aniline. It is found that the rate of corrosion depends on the type of inhibitor and
its concentration. The rate of corrosion decreases by increasing the amount of
inorganic additives from 9.72% to 80.14 %, depending on organic compounds and
their concentrations. These compounds verify Langmuir and Flory-Huggins
isotherm. Thermodynamic parameters are also reported.
