Identification and characterization of resistate minerals containing uranium and thorium
A set of natural matrix Standard Reference Materials were developed by the National Bureau of Standards for analytical methods evaluation. These materials were analyzed using a KF fusion procedure and an acid dissolution procedure. The latter method yielded radioactive concentrations that were 15–20...

| description | A set of natural matrix Standard Reference Materials were developed by the National Bureau of Standards for analytical methods evaluation. These materials were analyzed using a KF fusion procedure and an acid dissolution procedure. The latter method yielded radioactive concentrations that were 15–20% lower then that of the former. This was thought to be due to a fraction of the sample, “resistates,” that did not dissolve during the dissolution. In this study, HF dissolutions were conducted on NIST natural matrix SRMs, in which ~0.08% of total sample mass remained after dissolution. The acid resistant residual materials were concentrated, then dissolved using a LiBO

fusion procedure and were found to contain a considerable fraction of the uranium and thorium. |
