Multivariate Approach to Detection of Uranium Using LIBS
Original language description
This work aims to study the possibilities of LIBS concerning the detection of uranium precipitated in sandstones. The main challenge in uranium detection is its complex emission spectrum with very high density of spectral lines. As is it stated by Chinni et al. the number of uranium lines measured using a hollow cathode discharge lamp exceeds 5000 in the range 384.8 to 908.4 nm. Considering the spectral line broadening such line density significantly exceeds resolution of usually utilized spectrometers. In this paper two new analytical approaches are suggested to determine the relative content of uranium in the studied specimen. Prior to the LIBS technique the X-ray fluorescence analysis (XRF) was utilized for uranium presence verification. To employ this task an orthogonal double-pulse (DP) LIBS setup was utilized in order to reach high sensitivity, maintaining low crater diameter, subsequently enabling high spatial resolution chemical mapping.
