Methods for removing water from iodine (I2)

A method of removing water from a mixture of iodine (I2) and water, the method comprising:

• providing a mixture comprising iodine and water, wherein the mixture has a water concentration of from about 500 ppm to about 5,000 ppm by weight;
• and
• contacting the mixture with a solid adsorbent to selectively adsorb water from the mixture,
• wherein the adsorbent is selected from the group consisting of:
• molecular sieves having a pore diameter of 3 Å-5 Å, nickel (II) iodide (NiI2), and hydrotalcite,
• wherein after the contacting step, the water content of the mixture is 100 ppm or less by weight.
