The trace determination of inorganic cations in brine solutions using ion chromatography
- Los Alamos National Lab., NM (United States)
With the advent of ion chromatography, the determination of inorganic ions in aqueous solutions has been relatively straightforward. However, there are significant complications when ion chromatography is used to determine trace concentrations of inorganic ions in brine matrices. The analysis is further complicated when the sample is radioactive and the sample volume is limited. A Dionex DX-500 ion chromatograph with Dionex CG12/CS12 columns and suppressed conductivity detector was used. Several method and instrument parameters (i.e., eluents, flow rates, pretreatment columns) were investigated. The detection limits for ammonium, alkali and alkaline earth metals are on the order of 50-100 ug/L.
