Ion Removal

Idaho National Laboratory

Contact INL About This Technology

Technology Marketing Summary

INL’s ion removal technology leverages the ability of phosphazene polymers discriminate between water and metal ions, which allows water to pass through the membrane while retaining the ions.

Description

The inherent chemical and thermal stability of the phosphazene polymers are an added strengths for separating and dewatering metal-ion-containing solutions.

Benefits

-      Dewaters ion-containing solutions,

-      Discriminates between water and metal ions, and

-      Maintains chemical and thermal stability.

Applications and Industries

Ion dewatering, dewaterization, separating ions, ion reduction

Solution dewatering with concomitant ion removal
One of the biggest needs in the separations and waste handling and reduction area is a method for dewatering ion-containing solutions. Unexpectedly, it has been found that phosphazene polymers can discriminate between water and metal ions, allowing water to pass through the membrane while retaining the ions. This unexpected result, along with the inherent chemical and thermal stability of the phosphazene polymers, yields a powerful tool for separating and dewatering metal-ion-containing solutions.
