The behaviour of (226)Ra in high-volume environmental water samples on TK100 resin

Accurate, low-level measurement of (226)Ra in high volume water samples requires rapid pre-concentration and robust separation techniques prior to measurement in order to comply with discharge limits and drinking water regulations. This study characterises the behaviour of (226)Ra and interfering el...

Descripción
Sumario:Accurate, low-level measurement of (226)Ra in high volume water samples requires rapid pre-concentration and robust separation techniques prior to measurement in order to comply with discharge limits and drinking water regulations. This study characterises the behaviour of (226)Ra and interfering elements on recently developed TK100 (Triskem International) extraction chromatography resin. Distribution coefficients over a range of acid concentrations are given, along with an optimised procedure that shows rapid pre-concentration and separation of (226)Ra on TK100 resin is achievable for high volume (1 L) water samples without the need for sample pre-treatment.
