Abstract:
A mobile phase including a lithium salt flows through a stationary phase including an oxygenated metal compound with affinity to the lithium salt through a Lewis acid-Lewis base interaction so that the oxygenated metal compound captures the lithium salt through the Lewis acid-Lewis base interaction. An eluent flows through the stationary phase to release the lithium salt captured by the oxygenated metal compound into the eluent. The eluent includes a Lewis base or a Lewis acid that disrupts the Lewis acid-Lewis base interaction between the lithium salt and the oxygenated metal compound. The eluent including the released lithium salt is collected after the eluent flows through the stationary phase.
