| 中文摘要 |
| 将同一份样品通过两根阴离子交换树脂柱在浓盐酸和浓硝酸介质中分离钚和铀,用过氧化氢和亚硫酸对钚进行氧化还原作用,用稀盐酸冼提铀和钚.最后,微量钚和铀分别与10μg钼载体电沉积在不锈钢盘上,用α-谱仪测其α放射性.铀回收率为100%,钚的回收率平均为63%,但由于不够稳定而采用加内标方法校正回收率.本方法因采用联合分析手段,比以往方法快且样品用量减少到普通方法的1/10左右. |
| 英文摘要 |
| Plutonium and uranium in a plant sample ash was simultaneously determined studied by using anion exchange resin columns, and concentrated hydrochloric acid and akric acid. At the final stage of the determination of the nuclides, each of them was electrodeposited together with a little amount of molybdenum carrier onto a stainless steel plate and measured by α-ray spectrometer. The recoveries of uranium and plutonium from the plant samples determed by adding internal standard 236Pu was 100% and 63%, respectively. |
