I have talked to Doug about me writing a scholarly paper on all commercial methods of water treatment. I couldn't really begin until August since I'm currently writing grant proposals. It would be simple to review iodization methods since there is a body of knowledge already in the journals. As for testing different containers, it would be a simple matter of sealing Potable Aqua in various containers for the required amount of time and then determining the iodine concentration the dissolved pill affords in a known quantity of water. This could be easily done by UV spectroscopy.<br><br>Andy Osborne Ph.D, chemistry
