TEVA Resin
Extraction Chromatographic Resin
TEVA Resin
Applications
Separation of tetravalent actinides (Th⁴⁺, Pu⁴⁺, Np⁴⁺)
Highly selective separation of Tc (VII) (⁹⁹Tc)
Separation of hexavalent actinides (U⁶⁺, Np⁶⁺)
Determination of trace radioactive nuclides in environmental and nuclear industry samples
Core Advantages
Broad actinide coverage
Simultaneous adsorption of tetravalent and hexavalent actinides
High Tc selectivity
No interference from fission products, complete separation from Mo
Strong acid resistance
Stable performance in 1–12 M HNO₃, suitable for high-acid samples
Good compatibility
Can be used in series with other resins (UTEVA, TRU) for complete separation system
