“Quantification of technetium-99 in wastewater by means of automated on-line extraction chromatography – anion-exchange chromatography – inductively coupled plasma-mass spectrometry.” 

Warum Technetium messen? 

With more than 30 million medical applications annually, ^99mTc is the most widely used radioisotope. Nevertheless, the discharge of ^99mTc and its radioactive nuclear isomer ⁹⁹Tc through medical facilities into the aqueous environments is mostly unknown. This is related to the low absolute Tc mass used in medical examinations and consequent trace levels of Tc emitted from respective facilities. In this work, a new approach employing automated on-line extraction chromatography and anion-exchange chromatography was ….
