A TODGA based extraction chromatographic resin containing an ionic liquid was used for the separation of actinide ions such as Am and Pu from samples such as lean effluents emanating from laboratory waste, environmental water as well as soil samples adjacent to a nuclear plant site. The methodology involved feed adjustment to 3 M HNO followed by conditioning of the column, loading, washing (3 M HNO), and elution of the actinide ions. The elution of Am was done using EDTA in a buffered medium (1 M guanidine carbonate) while that of Pu was carried out using a mixture of 0.5 M oxalic acid and 0.5 M HNO. The elution peaks were sharp with almost no tailing suggesting the efficiency of the separation method. The results obtained were compared with the literature results which suggested the high efficiency of the present method.
采用基于 TODGA 的含离子液体的萃取色谱树脂，从贫化流出物、环境水以及核电厂附近土壤等样品中分离锕系元素离子，如 Am 和 Pu。该方法包括将进料调整至 3M HNO3，然后对柱进行预处理、装柱、洗涤（3M HNO3）以及洗脱锕系元素离子。Am 用缓冲介质（1M 胍碳酸盐）中的 EDTA 洗脱，而 Pu 则用 0.5M 草酸和 0.5M HNO3 的混合物洗脱。洗脱峰很尖锐，几乎没有拖尾，表明分离方法的效率很高。所得结果与文献结果进行了比较，表明本方法具有高效性。
