MOF-based homogeneous ion exchange membrane for high-efficiency magnesium-lithium separation

Key Points

• The aim is to develop a high-efficiency membrane for the separation of magnesium and lithium.
• Utilized a metal-organic framework (MOF) for membrane construction.
• Conducted tests on the performance of the membrane in ion exchange processes.
• Evaluated the efficiency of lithium separation from magnesium in salt lake brines.
• Achieved higher selectivity for lithium compared to magnesium.
• Demonstrated improved permeability and efficiency in recovery rates.
• Showed potential for improved industrial application in lithium extraction.
