Abstract
This thesis presents improved analytical methods for rapid and
automated determination of plutonium and neptunium in
environmental samples using sequential injection (SI) based
chromatography and inductively coupled plasma mass spectrometry
(ICP-MS). The progress of methodology development in this work
consists of 5 subjects stated as follows:
1) Development and optimization of an SI-anion exchange
chromatographic method for rapid determination of plutonium in
environmental samples in combination of inductively coupled
plasma mass spectrometry detection (Paper II);
(2) Methodology development and optimization for rapid
determination of plutonium in environmental samples using SIextraction
chromatography prior to inductively coupled plasma
mass spectrometry (Paper III);
(3) Development of an SI-chromatographic method for
simultaneous determination of plutonium and neptunium in
environmental samples (Paper IV);
(4) Investigation of the suitability and applicability of 242Pu as a
tracer for rapid neptunium determination using anion exchange
chromatography in an SI-network coupled with inductively coupled
plasma mass spectrometry (Paper V);
(5) Exploration of macro-porous anion exchange chromatography
for rapid and simultaneous determination of plutonium and
neptunium within an SI system (Paper VI).
The results demonstrate that the developed methods in this study
are reliable and efficient for accurate assays of trace levels of
plutonium and neptunium as demanded in different situations
including environmental risk monitoring and assessment,
emergency preparedness and surveillance of contaminated areas.
