Determination of lithium in brine.

Lithium is a soft metal which is used for many applications, for example, in the manufacturing of high-temperature lubricants and heat-resistant glass as well as in the battery industry. It is gained from brines and high-grade lithium ores. Depending on the concentration of the brines and ores the production is worth the extraction or not. Here, a method is shown to determine the lithium content in brines potentiometrically.
