Separation of Lithium by Ion Exchange Chromatography ...
Small amounts of lithium were separated from large amounts of sodium, potassium, calcium and magnesium ions. The separation was performed by a cation exchange chromatographic method. Amberlite IR‐120 was used as cation exchanger and a mixture of methanol (9 volumes)‐hydrochloric acid (1 volume) was employed as eluent.

Separation Science and Technology - Taylor & Francis
Aug 20, 2006 · Lithium Type X Zeolite as a Superior Sorbent for Air Separation. Li-X, Ba-X, and Li-A zeolites are prepared by ion exchange with the commercial Na-X (13X) and Na-A (4A) zeolites. At the ambient temperature (298 K), only Li-X exhibits a significant enhancement of the N 2 /O 2 adsorption selectivity over the commercial zeolites.
Equipment for lithium isotope separation
c. Ion exchange systems specially designed for lithium isotope separation, and specially designed component parts therefor; d. stone exchange systems (employing crown ethers, cryptands, or lariat ethers) specially designed for lithium isotope separation, and specially designed component parts therefor.
Extraction of lithium from primary and secondary sources ...
Separation of lithium and magnesium is difficult because they exhibit many stone similarities. However, by utilizing the high charge density of Mg 2 + which is twice that of Li + with almost the same ionic radius and its easy hydrated properties, Zhao et al. (2013) reported a separation method using LiFePO 4 /FePO 4 as electrodes .
Grease Bleed Separation - What You Need to Know
Oct 18, 2018 · Is Grease Bleed Separation Normal. Small occurrences of “static” grease bleed separation are considered to be normal, under normal operating conditions. Separated oil in the form of small pools or on the surface of grease pails or containers can be reincorporated back into the grease product by stirring.
