This thesis describes novel methods for the determination of selenium at the ultratrace level. The introduction reviews the techniques currently employed to determine selenium, and outlines the need for a highly sensitive and precise analytical method. Chapters two and three describe the determination of selenium by differential pulse polarography and differential pulse cathodic stripping voltammetry respectively. The application of these methods to the analysis of soils and plant materials is also reported. The determination of selenium by microwave plasma emission spectroscopy is described in chapter four. However, because emission spectroscopy was not sufficiently sensitive for the low level determination of selenium, electrodeposition and ion exchange techniques were investigated for the preconcentration of selenium. The results of this work are presented in chapter five. Finally, the combination of electrodeposition and microwave plasma emission spectroscopy for the low level determination of selenium is reported.
