| Abstract: | This paper was written on the basis of Literature[1]. The compound, 4. 5-benzo-solenium was extracted by 2, 3 DAN mixed with QuadrivaLemce Solenium trom the samples by meanss of the catalyst, cyclo-hexane under the comditin of PH1.5-2.0. The trace selenium from the crude tobacco was determined by fluorometry. the ressult is iarisfactory. |
