对萨凡纳河实验室的萨凡纳河废物进行的常规分析偶尔会发现，废物中的汞浓度超过0.200 mg L− 1 RCRA限值。在一个特殊的、允许的净化项目中，离子交换树脂被证明可以有效地从实验废物中去除溶解的汞。离子交换材料是Duolite™GT-73，一种具有硫醇（S-H）官能团的聚苯乙烯/二乙烯基苯树脂。由于该树脂在净化项目中表现出的有效性，它已被投入使用，或正在考虑与其他几个现场放射性废物流一起使用，作为可靠的汞去除介质。
Routine analyses of Savannah River Laboratory wastes at the Savannah River Site occasionally reveal Hg concentrations in the waste in excess of the 0.200 mg L−1RCRA limit. An ion exchange resin was demonstrated to be effective for the removal of dissolved Hg from experimental waste in a special, permitted decontamination project. The ion exchange material is Duolite™GT-73, a polystyrene/divinylbenzene resin with thiol (S-H) functional groups. As a result of the resin's demonstrated effectiveness in that decontamination project, it has been placed in use or is under consideration for use with several other Site radwaste streams as a reliable medium for Hg removal.
