This study aims to fabricate monovalent cations selective membranes through Layer-by-Layer (LbL) assembly with ion-imprinting introduced. Nickel ions (Ni2+) were introduced into the polycation of polyethyleneimine (PEI) as template and then modified the ultrafiltration membrane through LbL assembly followed by glutaraldehyde (GA) crosslinking and reduction After eluting the template, ion-imprinting channels with specific size were formed in the modified layer. These channels enhanced the water flux with the selectivity for Na+/Mg2+ improved 2.25 times simultaneously compared to the non-imprinted membrane. Besides, the membrane preparation conditions were optimized and the optimum selectivity of 4.16 was achieved. We analyzed the mechanism of improving separation performance via ion-imprinting technol. and believed that this environmental-friendly method provides a new road to fabricate monovalent selective membrane for seawater softening and lithium extraction from magnesium-rich brine. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Application of 7447-41-8).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Application of 7447-41-8
