Development of immobilization method for radioactive iodine using an inorganic composite sintered body

在这项研究中，放射性碘的固定方法，使用无机纳米复合烧结体（沸石/磷灰石纳米复合材料）已开发。纳米复合材料中碘含量大于5wt%。蒸馏水中碘的留存率大于99%。无压烧结法制备的纳米复合烧结体致密性好。这种无机复合烧结体是一种有前途的替代普通玻璃化过程。

In this study, the immobilization method for radioactive iodine using an inorganic nanocomposite sintered body (zeolite/apatite nanocomposite) have been developed. The iodine content in the nanocomposite was more than 5wt%. The iodine retention rate in distilled water was more than 99%. The nanocomposite sintered body fabricated by pressureless sintering method was well densified. This inorganic composite sintered body is a promising alternative to the common vitrification process.
