Detection of corrosion-induced metal release from tinplate cans using a novel electrochemical sensor and inductively coupled plasma mass spectrometer

► A novel electrochemical sensor was designed. ► Corrosion-induced metal release was investigated by ICP-MS and the sensor. ► The correlation between electrochemical parameters and ICP results was analyzed. ► The internal surface morphology of the cans was characterized by AFM. ► A metal release mechanism was proposed.
