ORNL advancing LDH sorbent to recover lithium from geothermal brine wastes
Green Car Congress
JANUARY 22, 2020
These plants pump hot water from geothermal deposits and use it to generate electricity. The LDH sorbent is made up of layers of the materials, separated by water molecules and hydroxide ions that create space, allowing lithium chloride to enter more readily than other ions such as sodium and potassium. The technique is very sensitive to hydrogen atoms, making it ideal for studying water.
