- Abstract:
-
A new method for the simultaneous recovery of U, Th and Pb from ca. 0.5 g calcium carbonate samples for the purpose of U-(Th)-Pb geochronometry is presented. The protocol employs ion-exchange chromatography. Standard anion exchange resin (AG 1-X8 100-200 mesh) was used as the static phase, and 90% acetic acid was used as the mobile phase to elute the unwanted matrix components; dilute nitric acid was used to elute the U, Th and Pb. Blanks of 1.8 pg Th, 6.4 pg Pb and 8.4 pg U were obtained. Th...
