Iodine (I2, CAS 7553-56-2) is a dense, blue-black crystalline solid (density about 4.9) that sublimes into a violet vapor and dissolves only slightly in water. Much of the U.S. supply comes from Oklahoma brines. Iodine is used in X-ray contrast media, disinfectants and povidone-iodine, animal feed supplements, LCD polarizing film and catalysts. Liquid storage usually involves iodine solutions or iodophors, which stain and are oxidizing. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
Nylon is the most economical tank material for Iodine, rated Excellent. PVDF (Kynar®) and HDPE are also rated Good or better. Avoid CPVC fittings and 316 stainless steel hardware. Rated Fair (contact us before use): polypropylene tanks and polypropylene fittings.
