开发利用海水化学资源是缓解陆地矿产资源危机的有效途径,功能分离材料则是海水化学资源高效提取的关键。重点介绍了以离子交换膜、离子筛和吸附剂为代表的功能分离材料及其在海水制盐和海水提取钾、锂、铀的应用现状,并对其发展趋势进行了展望。
It was an effective way for remitting the crisis of mineral resources on land by exploiting the marine chemical resources, and the functional separation materials were the key for obtaining resources from seawater effectively. As the representation of functional separation materials, ion exchange membrane, ion-sieve and adsorbent were introduced with respect to them development and application in natrium, potassium, lithium and Uranium were recovered from seawater, and the trend of their development was predicted.
