Determination of uranium in natural waters by neutron activation analysis

A rapid procedure has been developed for the measurement of uranium in natural waters using thermal neutron activation and anion-exchange separation of radio-uranium from ethanol/HCl solvent mixtures. Detection limits of 0.05 ppB have been achieved with analytical precisions of +-10--30 percent. Results of uranium analyses by this procedure and by fluorometry are compared for natural water samples from Alaska and New Mexico.
