Artificial mineralization of radioactive iodine using both mechanochemical and dry-gel conversion hydrothermal routes

In this study, a new conversion method via both mechanochemical and hydrothermal routes has been developed in order to realize a technological fixation of radioactive iodine into an artificial sodalite mineral. Based on the powder X-ray diffractions of crystal phases during above two processes, the low-temperature fixationmechanisms of iodine as a mechanochemical effect towards zeolite crystals were indicated.
