“…Similar arguments can also be suggested to account for Fe release, because its limiting values agree quite well in this case with the sequence of stability constants of iron complexes with the majority of the ligands considered [36][37][38]. The sole exceptions are the exceedingly low Fe releases found at pH = 4.0 in the presence of citric and malic acids (see Fig.…”

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.

“…For the Ni-tartrate system, there is considerable disparity in the published stability constants: for an ionic strength of 0.1 mol dm À3 at 293-298 K, values for log K have been reported as 3.01 [39], 3.07 [40], 4.68 [41,42], and 5.42 [43]. In the presence of tartarate at 0.01 mol dm À3 KNO 3 , pH 5.5, the SSCP wave for Ni was shifted to more negative potentials.…”
