从核废物中有效和具有成本效益地去除放射性高锝酸盐阴离子是缓解长期核废物储存问题的一个关键挑战。传统的材料，如树脂和层状双氢氧化物（LDHs）进行了评估，其高锝酸盐或过氯酸盐（非放射性替代品）的去除能力，但有改进的能力，选择性和动力学方面的空间。一系列功能化的分级多孔框架进行了评价，在其他竞争阴离子的存在下，他们的过氧化氢去除能力。
Efficient and cost-effective removal of radioactive pertechnetate anions from nuclear waste is a key challenge to mitigate long-term nuclear waste storage issues. Traditional materials such as resins and layered double hydroxides (LDHs) were evaluated for their pertechnetate or perrhenate (the non-radioactive surrogate) removal capacity, but there is room for improvement in terms of capacity, selectivity and kinetics. A series of functionalized hierarchical porous frameworks were evaluated for their perrhenate removal capacity in the presence of other competing anions.
