A chemical methodology has been selected to isolate and concentrate select trace fission product (FP) elements from separated Pu for nuclear forensics. The methodology employs several different resins and eluents to chromatographically separate U and the FP elements of interest into their own fractions. The U, rare-earth element, Cs, and Ba fractions were isolated with relative yields of ≥ 73.8%, ≥ 80.7%, ≥ 98.5%, and ≥ 98.0%, respectively. The methodology was able to successively isolate select FP elements on the order of 10–10 g out of much larger samples of Pu.

分离钚中的痕量裂变产物元素,用于核法证学

已选择化学方法从分离的 Pu 中分离和浓缩精选的痕量裂变产物 (FP) 元素,用于核法证学。该方法使用几种不同的树脂和洗脱液,通过色谱法将 U 和感兴趣的 FP 元素分离成各自的馏分。U、稀土元素、Cs 和 Ba 组分的分离率分别为 ≥ 73.8%、≥ 80.7%、≥ 98.5% 和≥ 98.0%。该方法能够从更大的 Pu 样品中连续分离出 10–10 g 数量级的精选 FP 元素。
