摘　　要：在实验室条件下自制一系列碱金属蒸气吸附剂，通过脱碱性能比较验证了吸附剂对碱金属蒸气的吸附不仅与吸附剂的化学成分有关，还与吸附剂内部的孔结构有关；XRD结果表明，煤灰中的主要成分对碱金属蒸气具有一定的脱除能力；各吸附剂对碱金属蒸气的吸附性能在有水蒸汽条件下的碱容量均高于无水蒸汽条件下的碱容量，对碱金属蒸气具有较强吸附性能的是自制样GM6、高岭土和活性氧化铝．Six nature minerals and six self-made sorbents were used to remove alkali metal vapor in a self-made alkali metal vapor removing apparatus. One kinds of active constitutes of self-made sorbents is coal ash, which XRD resuits indicate that coal ash has the property to remove alkali metal vapor. Resuhs proved that the sorbent reactivity depends on not only its content of active constitutes but also its structure. It was found that kaolinite, activated alumina and self-made sorbent GM6 are very efficient for alkali metal vapor removal.
