Oxidation state of technetium electrodeposited on platinum
EMSL Project ID
12303
Abstract
The method of thermal ionization mass spectrometry (TIMS) is being developed for the highly sensitive determination of technetium. The technetium is deposited on the platinum mass spectrometer filament by electrodeposition; this has been confirmed by both liquid scintillation counting of the deposition solution and by secondary ion mass spectrometry (SIMS) analysis of the Pt disk. However, the valence state of the technetium will likely influence the ionization characteristics of the element during thermal ionization. The method of X-ray Photoelectric Spectroscopy (XPS) is capable of answering this question.
