The oxidation of several transition metal cyanides by illuminated colloidal titanium dioxide has been studied with attention to end products and rate of reaction. Tetracyanozinc, a weak complex, and ferricyanide, a stable complex were the primary focus. The rate of complex dissociation of ferricyanide was found to depend on pH. The rate of oxidation of cyanide was found to be the same both complexed and as alkali cyanide. Although the precipitation of metal oxide onto the catalyst occurred, there was no evidence that it interfered in the oxidation of cyanide.
