UTEVA Resin
Extraction Chromatographic Resin
UTEVA Resin
Core Applications
Highly selective separation and enrichment of U (VI)
Separation of tetravalent actinides Th⁴⁺, Pu⁴⁺, Np⁴⁺
Determination of trace uranium and thorium in environmental, geological, and nuclear samples
Analysis of uranium isotopes (²³⁵U, ²³⁸U) and thorium isotopes (²³²Th, ²³⁰Th)
Key Advantages
Ultra-high U selectivity
Separation factor >10⁴ from common metal ions (Fe, Al, Ca, Mg)
High capacity
Suitable for both trace and macro uranium separation
Simple elution
Low-concentration acid elution, easy post-processing
Can be used alone or in series
Combined with TRU resin to achieve complete actinide separation (U-Pu-Am)
Mature methodology
Widely used in environmental, geological, and nuclear facility sample analysis
