| Abstract: | Abstract Optimum conditions for the determination of rhenium by flame emission speetronetry vere ascertained. The mart mim signal emanates from a region immediately above the tip of the inner cone of fuel-rich oxygen-acetylene flame. The sample was introduced as a solution in cyclohexanone by a sprayer-burner. Emission intensity at 3460 Å vas measured. In molybdenite flue dust, after normal dissolution steps, rhenium(VTl) vas extracted from 1.8–3.6 N H2SO4 vita cyclohexanone and the organic phase, vas. sprayed directly into the flame. Detection limit is 2.5 μg/al. |
