Title: Alternative Non-Acid Eluants for Spherical Resorcinol-Formaldehyde

Abstract

Small-column ion exchange (SCIX) units installed in or near high-level waste tanks to remove Cs-137 from highly alkaline solutions are among the waste treatment plans in the DOE Complex. Spherical Resorcinol-Formaldehyde (sRF) is the ion exchange (IX) resin under consideration for SCIX at the Hanford site. The elution step of the multi-step IX process is typically done with nitric acid. An acid eluant is a potential hazard in the event of a spill, leak, etc. because the waste tanks are made of carbon steel. Corrosion and associated structural damage may ensue. A non-acid eluant may be a viable alternative. It will eliminate the need for special acid handling requirements within the tank farms.
