Innovative Highly Selective Removal of Cesium and Strontium Utilizing a Newly Developed Class of Inorganic Ion Specific Media

Co-authored with Northwestern University materials chemists, this work introduces a new class of inorganic ion-specific media for the highly selective removal of cesium and strontium. It was presented at WM2009 in March and, in revised form, at ICEM2009 in October.

Conference Paper

The scientist behind this work is Fluid Tech's Chief Technology Officer. Mark S. Denton led media technology at Kurion, Inc. during the Fukushima Daiichi response (the affiliation printed on the paper), and the isotope-specific media science documented here is the foundation of Fluid Tech's WTZ® and FHA products. The media and systems in this paper were Kurion's; Fluid Tech's current products are described under Ion Exchange Media. The summary below is for reference only; full details are in the cited paper.

01 Overview

Highly selective removal of cesium and strontium is critical for waste treatment and environmental remediation. Cesium-137 is a beta-gamma emitter and strontium-90 a beta emitter, with half-lives of about 30 and 29 years respectively. Both are present at many nuclear sites, including the wastewaters at Washington State's Hanford site. The paper presents a newly developed class of inorganic ion-specific media for their selective removal.

Summary written from the published abstract. It reproduces no proprietary data, methods, or results.

02 Why it matters

  • Cs and Sr set the dose: these two isotopes dominate the radiological hazard of most legacy liquid waste.
  • Materials chemistry, not just process engineering: the media class was developed with a materials chemist, and the paper was presented twice in 2009.
  • The road to Hanford 105-KW: selective cesium and strontium capture is the same job WTZ® and FHA did at the Hanford K West basin fifteen years later.
