The iodine content in the wet grinding samples was significantly higher than that in the dry grounding samples. Comparative analysis shows that the crystal grains of iodosodalite in the solidified body obtained by wet grinding treatment are relatively well formed; that is, after hydrolysis treatment, the structure of 4A zeolite has changed ...

Iodine is prepared in the laboratory by heating a mixture of KI, MnO 2 and concentrated H 2 SO 4. Idonine is formed by heating this mixture. Iodine is a solid but it readily converts into vapor state on heating. The vapors of iodine obtained from the above reaction are condensed at the bottom of an ice-cold cup to obtain iodine as a solid.
