Abstract
Oxygen and fluorine have been simultaneously determined by 14-MeV INAA in samples containing boron. Both boron and fluorine can cause seriou s interferences in the determination of oxygen. The fluorine and boron interference corrections for oxygen determination have been determine d to be 0.43 +/- 0.01 and 0.0832 +/- 0.0017 apparent g oxygen per g of fluorine and boron, respectively, for our system. Boron can be determ ined in the same sample by a second irradiation. Mutual interferences have been evaluated and the procedure has been applied to NIST SRM and several other compounds.
