Uranium and Thorium

Uranium and thorium are naturally occurring elements found at trace levels in the environment. The determination of these two metals is often complicated due to interferences present in the sample matrix. Solvent extraction and sample preconcentration/pretreatment methods traditionally used prior to sample analysis are usually time-consuming and complicated. Chelation ion chromatography combines selective chelation concentration with analytical separation and specific detection. Chelation concentration preconcentrates uranium and thorium, eliminating alkali and alkaline earth metals from the sample matrix.
