The anodic behaviour and corrosion of tin in various concentrations (0.05-0.7M) of succinic acid were studied using cyclic voltammetry. The potentiodynamic anodic polarization curves exhibit active/passive transition. The active dissolution of tin involves one anodic peak. The cathodic curve exhibits one cathodic peak corresponding to the reduction of the passive layer. The ratio of the anodic charge/cathodic charge is more than unity indicating that the passive layer is very thin and the dissolution products are mainly soluble species. Additions of some polyethylene glycols to the succinic acid solution decrease the anodic peak current and shift the peak potential in the negative direction. These changes depend on the concentration and molecular weight of the polyethylene glycol added. The effect of the inhibitors decreases in the following order: (PEG) 6000 > (PEG) 4000 > (PEG) 1200 . The inhibition efficiency decreases with increase in temperature, suggesting physical adsorption.

“…When the surface is completely covered with the passive film, the anodic current density falls to a small value I pass . Some authors report similar mechanism for dissolution of tin anode in citric acid [20], maleic acid [21] and isobutyric acid [22]. The influence of sweep rate, ν, on potentiodynamic E/I curve of a tin electrode in 1.0 M tartaric acid at 25 • C is shown in Fig.…”

“…This is the reason why, in the last two decades, several investigations have focused on metal release from tinned containers, as well as on the formation of tinplate passivating films, which can be promoted by foodcontaining organic acids [9][10][11][12][13][14][15][16][17][18][19].…”

A voltammetric approach to an estimate of metal release from tinplate promoted by ligands present in canned vegetables

et al. 2008

A linear sweep voltammetric (LSV) approach is proposed for achieving rapid information on metal release from tinned containers into preserved vegetables. Chopped tomato and pea preserves were chosen as prototypes for acid and nearly neutral canned food, respectively. Metal release in these vegetables tinned into both bare and lacquered containers was compared with that found in synthetic samples containing some organic complexing agents (acetic, ascorbic, citric, malic, oxalic, pyroglutamic acids) present in the vegetables considered, thus showing that some of these components affected markedly the metal release in bare cans. These ligands were concomitantly found to also affect LSV profiles recorded in parallel at Sn and Fe electrodes in synthetic samples, causing the starting potential for their oxidation to be lower, the higher the ligand activity of the species considered. The data indicated that metal release and starting potentials for metal discharge are strictly related, so that LSV is able to provide rapid and useful information on the nature of the protective effect (electrochemical or physical) of tin on the steel underlayer, as well as on the extent of Sn and Fe release.
