Abstract

Lithium-aluminum-layered double hydroxide chloride (LDH) has been recently demonstrated to be a promising sorbent material for selective lithium extraction and recovery from geothermal brine. In this research, LDH samples synthesized from two different starting materials (alumina and gibbsite) and with two post-drying conditions (ambient-dried and oven-dried) as well as and Fe-doped LDH are studied using neutron vibrational spectroscopy. The results reveal differences in the ordering of interlayer water molecules. Thermochemical measurements of LDHs show that a higher interlayer ordering of water is directly related to the stability of gibbsite- and alumina-derived LDH. This corroborates with the previous work on increasing the stabilization of LDH via partial substitution of aluminum with iron. These findings on the properties of LDH have implications on their lithium extraction abilities and subsequent recovery.
