摘要：

Natural chabazite zeolite has been selected as the baseline treatment technology to compare the performance of emerging sorbent materials for the removal of Sr-90 and Cs-137 from contaminated process water. The resorcinol-formaldehyde resin, developed at Savannah River Site, is the first sorbent to be evaluated in this study. This paper summarizes the required contact times for maximum strontium and cesium removal, presents sorption isotherms in wastewater simulant and authentic wastewater, and defines the effects of elevated concentrations of K, Mg, Ca, and Na in wastewater for both sorbents.
