3 M Empore α-射线光谱-高分辨电感耦合等离子体质谱（HR-ICP-MS）快速分析环境样品中钚 贸易 研制了固相萃取用阴离子交换树脂盘。用Empore定量吸附微量钚 贸易 阴离子交换树脂盘（直径47 mm）以150-200 ml/min的流速从8 M HNO 3样品溶液中分离。用10 ml 8 M HNO 3和12 ml 9 M HCl洗涤圆盘，然后用15 ml 1 M HNO 3/0.03M抗坏血酸溶液定量洗脱Pu。用本方法从样品溶液中分离Pu所需的时间约为20分钟。分离后的钚采用α-射线光谱法和高分辨电感耦合等离子体质谱法测定，并应用于标准物质（IAEA-135）和环境土壤样品中钚的测定。分析结果与文献值基本一致。
A rapid analytical method of Pu in environmental samples by alpha-ray spectrometry and high-resolution inductively coupled plasma mass spectrometer (HR-ICP-MS) using a 3M Empore trade anion exchange resin disk for solid phase extraction has been developed. A trace amount of Pu was quantitatively adsorbed with an Empore trade anion exchange resin disk (47 mm diam.) at a flow rate of 150–200 ml/min from 8M HNO3sample solution. The disk was washed with 10 ml of 8M HNO3and 12 ml of 9M HCl and then the Pu was quantitatively eluted with 15 ml of 1M HNO3/0.03M ascorbic acid solution. The time needed to separate Pu from the sample solution with the present method was about 20 minutes. The separated Pu was determined with alpha-ray spectrometry and HR-ICP-MS. The present method was applied to the determination of Pu in the certified reference material (IAEA-135) and the environmental soil sample. The analytical results were almost in good agreement with the literature values.
