摘要: 锂及其化合物广泛应用于陶瓷、医药、空调、催化剂、高能电池和轻型锂铝合金等,又是热核反应必不可少的主要原料,人们对锂及其化合物的需求将与日俱增.目前,对锂离子具有特异选择性和记忆功能的无机离子交换体的研究尤为注目[1~5].本文叙述对Li+有记忆功能的尖晶石构造Li-Cu-Mn复合氧化物无机离子交换体的合成、结构及其离子交换性能.

关键词: 尖晶石, Li-Cu-Mn复合氧化物, 合成, 锂离子交换

Abstract: The title lithium-copper-manganese complex oxide, a spineltype metal oxide, was prepared by a coprecipitation/thermal crystallization method. Its Li+ extraction/insertion process was found to be a topotactic reaction. It had an ion-exchange capacity of 5.0mmol/g for Li+ and showed also a memorial ion-exchange property for Li+.

Key words: spinel, Li-Cu-Mn complex oxide, synthesis, lithium ion exchange
