extracting iodene

[skunkdude]

how would one go about extracting iodene from a diluted "water purifying" product?

[PYRO500]

First of all it's IODINE! and we need to know the concentration of iodine in your solution before we can advise anythig, you could sublimate it onto a piece of glass if the concentration was high enough

$50 says LL k3wl J here wants to make some NI₃. http://theforum.virtualave.net/ubb/smilies/rolleyes.gif

I don't think that anything is better for pranks than small amounts of it.

Berserker,what leads you to believe i'm kewl?

if you heat it which part comes off first the water or the iodine?....maybe there is a way to distill it off and allow it to crystilise inside the tube then scrape it out.

I have rarely had good results on extracting it by heating it, so I would just buy some. Its very hard to get, except for on ebay. The only down fall is that you have to buy like 2 lbs for about $100+

Skylighter sells it.

Yea, but that have restrictions on it (like 2 oz a year or something) and it is very expensive ($20 an oz I think). And they are really a hassle to order from. You have to provide a picture ID and a good photocopy of your drivers license and a lot of stupid shit.

you can extract iodine from seaweed.first burn the seaweed to ash then grind to a fine powder add the powder to nitric acid and distill the iodine gas that comes off.dont know what concentration of nitric acid you use.

I don't like aiding newbs, but for the others on the forum, consider the following reaction:

<font face="courier new" size=2>2NaI(aq) + 2HCl + H₂O₂ -> I₂(s) + 2NaCl(aq) + 2H₂O</font>

This works fine with common 6% H₂O₂ and 30% HCl, and the NaI can be bought at any pool store cheaply.
