Extracting lithium from seawaterAndrea GainiMaterials World
The researchers favor extracting metals from industrial wastewater, where they're rich and concentrated, as opposed to extracting metals from seawater. "The concentration of lithium in the ocean is very low, and because the concentration is so low, you need to process millions of gallons of water...
24). In each case, the HC solution is maintained at 0.6 M (seawater) and the concentration of the LC solution is then varied from 1.5 mM (river water) up to 0.594 M. The maximum Gibbs free energy is found in each case, as well as the value of φ that optimizes it. Our results...
Deep ocean water used in the present invention, are obtained from seawater at the depth of 200 m and below, and has a plenty of ion components including sodium ion (Na+), potassium ion (K+), calcium ion (Ca2+), magnesium ion (Mg2+), boron ion (B3+), chlorine ion (Cl−), carb...
Nevertheless, in a few cases, mainly lithium, extraction from seawater could provide amounts of metals sufficient for closing the cycle of metal use in the economy, provided that an increased level of recycling can be attained.doi:10.3390/su2040980Bardi...

PROBLEM TO BE SOLVED: To provide an equipment for efficiently separating and extracting lithium from a lithium-containing aqueous solution, such as seawater and geothermal water, by using a lithium adsorption plate.KOYANAKA HIDEKI古屋仲 秀樹
the ion-sieve adsorption method is regarded as the most promising one for extracting lithium from seawater and brines.In this review,the structure of LiMn2O4 is presented,and the development of lithium-ion insertion/extraction mechanisms is introduced as well.The synthesis method and modification of...
Researchers from the College of Chemical Engineering,Nanjing Tech University(Nanjing,China;www.njtech.edu.cn)have developed a new strategy for forming lithium ion-sieve membranes to achieve an efficient recovery of lithium ions from brine or seawater.Chemical Engineering Group...
Extracting drinking water from sea water, comprises binding elements of seawater, preferably sodium chloride, sodium bromide, sodium iodide, magnesium chloride, calcium chloride, further elements e.g. chlorine, magnesium, sulfur, calcium, potassium, bromine, boron, silicon, fluorine, argon, lithium, ...
