Sažetak
The effect of cysteine on the electrochemical and corrosion behaviour of aluminium in salt solution was investigated. For this purpose, model salt solutions containing sodium chloride (3 wt %) and sodium chloride with cysteine, at the concentrations from 10-1 to 10-5 % (1:1), were prepared. The system was chosen to perform the corrosion processes which could take place in canned fish products where cysteine is one of the amino-acids containing sulphur in a molecular structure. Electrochemical investigation was prepared using potentiostatic polarisation method. From the potentiostatic polarisation data, corrosion current (icorr), corrosion potential (Ecorr), and polarisation resistance (Rp) were calculated. The inhibition efficiency (n / %) of added cysteine was also calculated. Redox potential and pH of test solutions were also determined.
