Safety considerations involving the use of the flammable solvent rule out the solvent extraction of the iodine as a class experiment for larger groups. However, with suitable small groups, extraction of the aqueous iodine into a non-polar solvent to show its characteristic purple colour could be carried out on a test tube scale, using only a few cm 3 of the solvent.

For total iodine extraction from soils less than 0.5 mm, particle-sized soil was used. Total iodine content in the selected soil samples was determined by single extraction method with tetramethylammonium hydroxide (TMAH) modified according to Yamada et al. (1996) and Fecher et al. (1998). 100 mg of finely ground soil and 5 ml 5% TMAH (Alfa Aesar, Karlsruhe, Germany) were added to 15 ml ...
The present invention relates to processes for extracting iodine from mother liquors, natural brines and the like. In United States Patent No. 1,853,621 to Jones and Grebe, there is described a procedure for extracting iodine from a natural iodiferous brine in which the brine is. first acidified, then electrolyzed or otherwise oxidized to liberate iodine, such iodine then being separated from ...
Extracting Iodine From Tincture: I couldn't find any guides in Instructables on isolating/extracting Iodine from tinctures and drying it, so I decided to make one myself.NOTE: I can't stress this enough, WEAR GLOVES AND SPARE CLOTHES OR LAB COAT, Iodine is quite a messy element now…
