Abstract
THE sodium fluoride fusion method is commonly used for the determination of minute amounts of uranium1. The sample to be tested is fused in a platinum crucible with sodium fluoride, and the fluorescence is measured in a fluorimeter. By this method, amounts of uranium down to 10−10 gm. can be determined in 0.2 gm. of fluoride.
