I know this is an old thread, but was wandering around the Hive, came across it, and thought, "Hey, since folks have posted a couple of quick and easy ways to get I2, and since 'How do I get I2?' is a commonly asked question, why dont I go ahead and post a method I came across?"
So here goes. I came across this method awhile ago, and dreamt that it worked very well.

Iodine Extraction
-----------------
Originally posted by cantstanditanymore
Ingredients:
1 pint tincture of iodine (7%)
3 pints hydrogen peroxide (3%)
1/2 cup distilled water
1/2 cup muriatic acid
Other things needed:
1 gallon jug
1 set rubber gloves - nothing says cook like iodine stained fingers!
coffee filters
more distilled water for rinsing of product
Put tincture, peroxide, acid, and distilled water in your clean gallon jug. (Note, as with all chem equipment, only clean it with distilled water.) Cap the jug and shake well. Set aside for 20 minutes or so. Go watch an episode of South Park while you wait. Pour off excess liquid. Take 2 coffee filters, placing one inside the other, and filter remaining product through the coffee filters. When filtration is complete, roll up product in filter and squeeze firmly to remove moisture. Transfer to clean set of coffee filters and rinse crystals with distilled water. Do this 4 times to clean your product. Once again, squeeze firmly to remove as much moisture as possible. Place product on clean, dry filters or in pyrex dish, and set in a dark place to dry. As soon as is dry, transfer product to dark, airtight container. Approximate yield, 16 grams.
