Hello James, The scientific term oxidation refers to the removal of an electron from an atom, molecule or particle, thus making that particle more positive. As colloidal silver is generally composed of positively charged particles, further oxidation (removal of more electrons) of these particles requires quite high amounts of energy. The reaction of UV light with water happens in this manner, I believe. UV light causes the production of Ozone (O3) in the water (which probably could oxidise elemental silver to Ag+), but which is short lived and devolves to Hydrogen peroxide (H2O2) and Oxygen gas (O2). H2O2 degenerates slowly into H2O and O2, but it is known that CS will actually stabilise H2O2, so maybe we end up with a colloidal silver sol along with some small amount of H2O2. Light energy is unlikely to directly effect colloidal silver, and although much is said about knocking the charge off the silver ions, as the charge is due to a deficiency of electrons it is hard to see how this might occur.
