AU158: Determination of Manganese in BrineInstrument Type: IC
Sodium chloride brines are used in chlor-alkali cells and must have low concentrations of alkali and alkaline earth metals to prevent membrane poisoning. When brines are prepared from seawater, the manganese concentration is also a concern. This application update uses the same separation conditions as AN 120, but alters the online sample preparation with the MetPac column to effectively concentrate manganese from 10 times more sample than used in AN 120.
