Ferrocyanide solution with uv light

om3gawolf_1362 - 20-9-2016 at 23:41

I've just finished reading about cyanide oxidation with uv light and ozone,
there's a bit that states iron cyanide solutions in uv light gives rise to iron hydroxide precipitate, an cn aqueous solution,
(but they have 4 missing potassiums from their article :mad:)

now my question is:
if this is pushed to the right by the light, and the iron hydroxide is filtered,
shouldn't the remainin' potassiums and cn's bond together if the uv is removed

I've used the search engine abit, and I've read most of the long, long cyanide thread,
but I think this is slightly different, so I thought i'd ask it here

A link to what you where reading may have helped.

Under some circumstances ferrous ions are reduced to ferric ions by light that's how blue prints where made. But you mention potassium ions, iron ions and cyanide ???

thanks for the answer,

what you mention is Cyanotype printing,
which is different because the mixture being exposed to light has a different make-up,
this is a 2 step uv/ozone based destruction of iron cyanides, but stopping before the ozonation process.
