In order to evaluate the immobilization of ~(129)I by uranophane that is expected to dominate the secondary uranyl phases during the corrosion of spent fuel in granite groundwater,uranophane has been synthesized in hydrothermal solution that contains KI,KI.

硅钙铀矿(uranophane)是UO_2在花岗岩地下水中氧化蚀变的主要次生矿物;~(129)I在核反应过程中的产率较高,在水-岩系统中的活动性强,在高放废物地质处置研究中倍受关注。
