摘要:

金属锂及其化合物广泛应用于各个领域,其需求与日俱增,是一种重要的战略资源。传统的从矿石中提锂步骤繁琐、能耗大,且资源量日益减少,因此,从液态锂源如盐湖卤水、海水中提取锂资源具有十分重要的意义。相关研究者对液态提锂的方法也进行了积极的探索研究,而离子筛型锂吸附剂以其绿色而高效的优势,引起了众多学者的关注,成为目前最有发展潜力的液态提锂方法之一。本文对离子筛型锂吸附剂进行了分类,综述了锰系氧化物、钛系氧化物以及掺杂型离子筛这3种典型锂离子筛型吸附剂的吸附机理、制备方法、吸附性能等方面的研究进展,分析比较了各自的优缺点,并指出离子筛型吸附剂目前存在的问题,最后对离子筛型锂吸附剂的改进及应用进行了展望。

Abstract:

Due to the growing demand and as an important strategic resource, lithium and its compounds play an important role in various fields. Traditional methods of extracting lithium from ore consumed a large amount of energy and the process was complicated. Therefore,it is of great significance to extract lithium from liquid lithium resources,such as brines and seawater. Active exploration of lithium extraction methods has been conducted by researchers,and the lithium ion sieve with its green and efficient advantages draws attention of scholars. It has become one of the most potential methods of extracting lithium from liquid lithium resources. In this paper,lithium ion-sieves were classified;the adsorption mechanism, preparation methods,and adsorption properties of manganese-based,titanium-based and doped lithium ion-sieves were summarized. Their advantages and disadvantages were compared and analyzed. The problems existed in lithium ion-sieves at present was pointed out. Finally,the improvement and prospect were suggested.

Key words: brine, ion-sieve, absorption, lithium
