    feldspar flotation as a quartz-purification method in

    The presence of feldspar in sediment samples poses a challenge to the separation of quartz and affects the chemical procedures for extracting the radioactive CNs 10 Be and 26 Al. Additionally, feldspar contamination reduces the 26 Al/ 27 Al ratio, thus hinders the accurate determination of 26 Al by accelerator mass spectrometry (AMS). Using fluvial sediment samples from Central Asia, which …
