Abstract
Accurately quantifying lanthanides is important in many fields including mining, manufacturing, and environmental chemistry. Lanthanides are components in commercial items including lamp phosphors, permanent magnets and catalysts. The most common analytical techniques for lanthanide quantification are: inductively coupled plasma mass spectrometry (ICP-MS), optical or atomic emission spectrometry (ICP-OES or ICP-AES) and neutron activation analysis (NAA). Each of these analytical techniques has unique benefits and limitations that are exacerbated by potential sample components. For example, ICP-OES has emission interferences, ICP-MS must overcome polyatomic interferences, and NAA may be limited by gamma energy emission interferences. These are particularly problematic due to the abundant similarities found within the lanthanide series. The work summarized in this thesis shows the ability of kinetic phosphorescence analysis (KPA) to quantify europium and terbium in the presence of additional lanthanides.
