I was going to say, I'm really interested in why iodine can't be distilled off, but then I remembered how low its boiling point is. Can you get it with fractional distillation? Is the boiling point far enough off from water that the first or last fractions could just be tipped out? I wonder what kind of iodine compounds you can precipitate out of solution... Then again, the cure might be worse than the disease. *goes to look up insoluble compounds*



Aha! AgI (silver iodide) is very insoluble, per my I-Chem textbook. So if you could 1. figure out and 2. produce a series of washes that started out with I(aq) and wound up with, for example, NaCl(aq) or other nontoxic dissolved salt, and then you could just distill off the water and carefully contain and discard the AgI precipitate. Do you know if dissolved iodine is usually neutral or ionic?
