OSTI ID:6068710
An ion chromatographic method has been shown to be applicable to determination of boron below 30 ppM in a sodium- and silicon-rich matrix. Determination of boron in frit and product glass was essential to understanding behavior of a process being developed to immobilize nuclear waste in borosilicate glass. With this method, glass samples are dissolved in hydrofluoric acid to convert boron to the tetrafluoroborate anion. The tetrafluoroborate anion concentration is determined by ion chromatography. The instrument is contained for analysis of both nonradioactive and radioactive samples.
