Abstract

<abstract> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <p>This work evaluates the corrosion resistance of the inner surface of the aluminium cans in guarana, cola flavoured and tonic water soft drinks using electrochemical impedance spectroscopy (EIS) measurements. The less aggressive electrolyte was tonic water. One time constant was identified for the aluminium can in contact with guarana and tonic water. In the most aggressive medium of cola flavoured soft drinks, two time constants were identified and a charge transfer resistance was obtained associated to a corrosion of aluminium in contact with the electrolyte.</p> </abstract>
