Introduction.—The identification of technetium in stars has been confirmed, thus establishing that stellar synthesis of this element is occurring. Recent developments in the analytical chemistries of technetium and rhenium have been reviewed, as has the extraction of rhenium from hydrochloric acid solutions a text describing the analytical chemistry of technetium and other man-made elements has been published. ... 

Progress in technetium chemistry obviously depends on sensitive analytical methods to detect this radioelemcnt, to efficiently separate it, and to determine technetium accurately. Several reviews on the analytical chemistry of technetium have been published [1-7]. Even the discovery of technetium was conclusive only because separation techniques known at the time for the homologous element rhenium were used 8. Furthermore, the detection of naturally occurring technetium or the determination of the element in the environment presupposed the application of highly sensitive methods. The effective extraction of pcrtechnctate into organic solvents for the isolation of technetium from fission product waste solutions is. in addition, an example of the significance of appropriate techniques in analytical chemistry.
