Isotopic analysis of uranium in natural waters by alpha spectrometry
K.W. Edwards
1968, Water Supply Paper 1696-F
A method is described for the determination of U234/U238 activity ratios for uranium present in natural waters. The uranium is coprecipitated from solution with aluminum phosphate, extracted into ethyl acetate, further purified by ion exchange, and finally electroplated on a titanium disc for counting. The individual isotopes are determined by...
