Abstract

Rhenium can be determined by atomic absorption in a fuel-rich acetylene–oxygen flame, using either de or ac electronics. Use of an organic solvent increases the sensitivity. Proper burner placement in the optical path is critical. Using three burners in a single-pass optical system, with optimum conditions, 1–2 ppm rhenium is readily detectable.
