- In some research that I was doing several years ago, I had the
- opportunity to develop a sensitive assay for peroxide formed in solutions of
- auto-oxidizing phenolic compounds. The test was based on iodide, with the
- sensitivity enhanced by using liquid starch (which forms a blue colored complex
- with the product). Tom tells me that he is using saturated LiOD in D2O. I
- will try to spend a couple hours in the lab this weekend and see what I can
- develop in the way of a sensitive spot test using a single drop of electrolyte.
- I think the main problem may be the strong base, which may have to be
- meutralized before proceeding with the test. I will post any methodology that
- I develop.
