Purification and Measurement of Acid Leachable Europium in Sands as an Aid in the Study of Sediment Transport

摘要

The use of europium labelled sand as an aid in the study of sediment transport has been suggested. A method for the purification of acid leachable europium is described. The final measurement is made by flame emission spectrometry using a nitrous oxide-acetylene flame. The usefulness of the method is limited by the natural levels of europium which, in the sand studied, was around 0.3 ppm. (Atomindex citation 14:787867)
