IONSIV Ion Exchangers for Radioactive Materials
If you need to remove radioactive cesium and strontium cations from
wastewater, you need to find out more about UOP’s innovative
IONSIV ion exchangers.
Our IONSIV product portfolio consists of two classes of materials,
zeolites and crystalline silicotitanates, both of which provide a
unique combination of selectivity, capacity and stability not available
from other ion exchangers.
Zeolites are crystalline hydrated alumino silicates, most commonly
of Na, K and Ca cations. Their structure contains channels and interconnecting
voids which are occupied by the cation and water molecules. The cations
are quite mobile and can usually be exchanged, to varying degrees,
by other cations in solution.
Crystalline silicotitanates (CST) are a new class of compound invented
by researchers at Sandia National Laboratories and Texas A&M University. UOP has recently
developed commercially available CSTs under a Cooperative Research and Development
Agreement with Sandia.
CSTs combine extremely high selectivity for cesium cations across
a broad range of pH conditions with high selectivity for strontium
cations in neutral and alkaline conditions.
