Sublimation of Iodine from Iodine Povidone

Connor Leech  Follow

Yes you can because it is in a complex with the povidone. You just have to heat it a little bit extra. This is because a complex is "tangled up" molecules. In this case it is Povidone and Iodine. Nile Red used a different process (liquid-liquid extraction), but here is the link. https://www.youtube.com/watch?v=FNf8PSda7iI

Yes, Ive seen Nile Reds video. Since he removed most of the polymer through his process, I was not sure if you could merely sublimate the iodine out. Any idea if what kind of heat you might need to do so?More
