Sažetak
The study of corrosion/inhibition process of tin in salt solution is still of great importance because of its huge application in food packaging. In this paper an inhibitory effect of pectin and ascorbic acid on the corrosion of tin in sodium chloride solution is investigated. For this purpose model solutions containing NaCl-pectin-ascorbic acid, at different concentrations, were used. The results of the investigations showed that ascorbic acid and pectin, at the concentrations of 50-200 ppm and 1-2 g/L, respectively, have an inhibitory effect on corrosion processes taking place at the tin electrode, so the higher ascorbic acid content the higher inhibitory effect is observed. The same effect is achieved with ascorbic acid/pectin mixture. In mentioned cases the synergistic effect of pectin in the model solutions is noticed, especially with addition of 200 ppm of ascorbic acid. Corrosion process of tin, in all investigated solutions, was under cathodic control.
