This report describes the results of cesium sorption kinetics and equilibrium isotherm tests with resorcinol-formaldehyde (RF) resin using Tank AN-105 simulated waste. These tests were conducted at the Savannah River Technology Center in support of the Hanford River Protection Project - Waste Treatment Plant (RPP-WTP). A crucial part of the current treatment process involves the removal of cesium from waste tank supernate solutions using columns containing SuperLig 644 resin. Due to concerns about the chemical and hydraulic performance of SuperLig 644 resin in large-scale operations, RF resin was evaluated as a potential alternative to the baseline material. Extensive testing was conducted at Pacific Northwest National Laboratory on various RF samples (both granular and spherical) obtained from different vendors. Three RF samples (two spherical and one granular) were subsequently delivered to SRTC based on initial screening results at PNNL, which indicated good performance for these materials. A small number of tests were then conducted at SRTC on the RF resin using non-radioactive simulant solutions to support development of a preliminary column performance model.
