锰基锂离子筛研究进展

Research Progress in Manganese-based Lithium-Ion Sieve

锰基锂离子筛因其对锂离子具有高选择性和循环吸附的稳定性成为当前工业上主流的卤水提锂工艺之一。基于文献的阅读和整理,介绍了锰基锂离子筛的概念,分析了对锰基吸附剂吸附原理常见的3种解释,并从掺杂改性和包覆改性两个方面分析了通过对锂锰氧化物进行改性调节其固液界面结构的研究现状,同时为今后的研究方向提出展望。

Manganese-based lithium-ion sieve has become one of the mainstream processes of lithium extraction from brine in the industry due to its high selectivity and stable cyclic adsorption of lithium ions.According to literature review and organization,the paper introduces the concept of manganese-based lithium-ion sieve,analyzes the three common explanations on the adsorption principle of manganese-based adsorbents,and describes the research status of modifying lithium manganese oxides to adjust the solidliquid interface structure.Meanwhile,the paper proposes the prospects for future research direction.
