Abstract:
Matrix effect is one of major problem of Inductively Coupled Plasma-Mass
Spectrometry (ICP-MS) technique. It will make inaccurate results. In some case the ratio of
uranium isotope is quite sensitive necessity such as 235U/238U ratio. Solid phase extraction by
using UTEVA resin is to separate uranium (U), thorium (Th) and other elements before using
ICP-MS measurement. This work tests the extraction process of 2 multi-element standard
solution and 2 geological samples. The experiment focus on percent recovery of U, Th, resin
recycling, and matrix effect of extracted-process. The results show that UTEVA resin is
highly selectivity for U/Th with other elements, then matrix effect is reduced. The other
benefit of this extraction process provides increase U and Th concentration in sample that can
be measured by quadrupole mass spectrometer (or ppb detection limit) and to improved
confidential result of unknown samples for nuclear forensics and safeguards aspect.
