Title: Evaluating Solid Sorbents for Recycling Wash Waters Containing Strontium and Calcium

Abstract

We have developed a system for rapid reduction of radioactive contamination and capture and recycling of contaminated wash waters called Integrated Wash-Aid, Treatment, and Emergency Reuse System (IWATERS). IWATERS prescribes the use of wash waters containing salt additives to enhance the removal of radionuclides from various surfaces and solid sorbents to remove the radionuclides selectively. One possible additive to the wash water is Ca2+ . However, the concentration of this ion can have a very strong detrimental effect on the ability of sequestration agents to sorb strontium effectively. A literature review, batch tests, and surface complexation modeling revealed a few sorbent options for Sr2+ in the presence of Ca2+. Engineered silicotitanate sorbents exhibited superior Kd values in the presence of Ca2+ but have significant drawbacks in cost and availability.
