The brines of the South American Puna contain a great amount of valuables ions. Among them, lithium has the highest economic value; therefore, its grade and recovery are of interest in the purification steps of the brine. ...

The chemical composition and the impacts of reject brine disposal from desalination plants on soils of the west of Rio Grande do Norte, Brazil, were evaluated. Soil samples in the 0.0–0.2 and 0.2–0.4 m profiles were collected ...

This short review covers the recent developments in electrochemical methods for the extraction of lithium from natural brines, seawater, and battery recycling electrolytes by ion-pumping mixing entropy cells and electrodialysis. ...

Lithium extraction from continental brines involves the evaporation of large amounts of water in open air ponds, in order to concentrate the brine. The evaporitic technology implies the evaporation of large water volumes, ...

The electrification of our world is driving a strong increase in demand for lithium. Energy storage is paramount in electric and hybrid vehicles, in green but intermittent energy sources, and in smart grids in general. ...

A highly selective LiMn2 O4 -Polypyrrole electrochemical cell for the extraction of LiCl from natural brine is described. Reproducible intercalation of Li+ in Lix Mn2 O4 (0 ≤ x ≤ 1) and Cl- in oxidized polypyrrole (PPy+) ...

A large amount of hydrocarbon reservoirs in the world are in the secondary recovery stage and improving this step in the exploitation of these reservoirs would greatly benefit the oil industry. Secondary recovery involves ...

The Andean plateau is a small region of South America extending between northwest Argentina, southwest Bolivia and northern Chile. It concentrates the largest global resources of lithium brines in its numerous salars. Of ...

Pirarucu (Arapaima gigas Schinz) farming has been encouraged and, among meat preservation techniques, the salting process is a relatively simple and low-cost method. The objective of this work was to study the sodium ...
