OK I missed your original post. I wrote the article you refer to. I am
a chemist and do know what is happening in this procedure so let's
start fresh.

What is it that needs more clarification on this topic? You ask the
questions and I will try to give a reasonable explanation.

I had a feeling you were the same person as the original post I pasted.
Sandy had the original question and I was trying to help. The only thing I
still don't understand is exactly what the "complex" is that drives the
Fe203 to dissociate and reform this complex with Cl-. Is it some kind of
hydrated Fe complexed with Cl-?

thanks,
