aluminum foil laminates are used in food packaging which contain chlorine dioxide disinfectant. Will the chlorine dioxide attack or oxidize the...

Aluminum is a not a very stable elements and reacts with
substances like steam, oxygen at slightly elevated temperatures and dilute and
concentrated acids.

Chlorine dioxide is a very efficient
disinfectant of water and this leads to its many applications in disinfecting food
products.

Aluminum reacts with chlorine dioxide to form
aluminum chlorite:

Al + 3 ClO2 -->
Al(ClO2)3

This reaction corrodes aluminum and acidic
conditions and high concentrations increase the rate of reaction. Plastics are not
affected by chlorine dioxide.

Some substances that can
react with chlorine dioxide to reduce it to chloride ions are borohydrates, highly
concentrated iodide, sulphurous acid, ferrous chloride manganese and vitamin C. It may
not be possible, though, to use many of these chemicals in food
products.
