Impurity distribution
Witrynaimaging the impurity distribution in ice cores can be refined and strongly improved. A novel cryogenic two-volume ablation chamber is paired with a rapid aerosol transfer system in order to achieve fast washout times (34 ms). In so doing, we are able to analyze ice cores for the first time using next generation LA-ICP-MS imaging … WitrynaThe present application discloses a lithium extraction method for an alkaline solution, in which a lithium adsorption material is used in an alkaline environment. Lithium ions in the alkaline solution are adsorbed, the lithium adsorption material is replaced with an alkaline high-lithium low-impurity solution, and then an acid solution is used for desorption, so …
