为了发展聚变反应堆氚增殖材料锂陶瓷(Li2TiO3、掺杂CaO的Li2TiO3、Li4SiO4和Li2O)的后处理技术，研究了锂陶瓷回收6Li资源的溶解方法及其锂溶液的净化方法，以去除辐照后的杂质(60Co)。在本工作中，用HNO_3、H_2O_2和柠檬酸(C_6H_8O_7·H_2O)等化学水溶液试剂从每个锂陶瓷粉末中溶解锂的比率都在90%以上。以8-羟基喹啉浸渍的活性碳为络合剂，在锂陶瓷溶解溶液中加入~(60)Co，去污率达97%以上。
In order to develop the reprocessing technology of lithium ceramics (Li2TiO3, CaO-doped Li2TiO3, Li4SiO4and Li2O) as tritium breeder materials for fusion reactors, the dissolution methods of lithium ceramics to recover6Li resource and the purification method of their lithium solutions to remove irradiated impurities (60Co) were investigated. In the present work, the dissolving rates of lithium from each lithium ceramic powder using chemical aqueous reagents such as HNO3, H2O2and citric acid (C6H8O7·H2O) were higher than 90%. Further the decontamination rate of60Co added into the solutions dissolving lithium ceramics was higher than 97% using the activated carbon impregnated with 8-hydroxyquinolinol as chelate agent.
