Sažetak
The inhibiting properties of several amines as surface active
substances and as corrosion inhibitors in acid solution was studied
by the a. c. polarographic method. The electrode processes of
cadmium and lead served as indicators of the inhibitor efficiency.
The inhibitions of the electrode processes, resulting in a decrease
of the a. c. polarographic wave, was found to increase in the
sequence: n-butylamine < pyridine < aniline < o-methylpyridine
< o-toluidine < 2,3 :. dimethylaniline < 2,6-dimethylaniline <
< quinoline < u-napthylamine. The investigations were-performed
in 1 N HCl04, H2S04 or HsP04. A stronger inhibitor · efficiimcy
was found in the H3P04 solution. The relation between the
inhibition and the pH of the solution showed that the RNff3 ion
inhibited considerably more than the neutral RNH2 molecules.
The influence of chloride ion on the rate of inhibited electrode
processes was also investigated. It has been found that the accelerating
effect does not depend on the nature of_ the investigated
amines and that there is a linear relation between the accelerating
effect and the chloride concentration.
