Abstract

Here, we present a method for concentrating radiocesium in seawater using ammonium molybdophosphate-polyacrylonitrile (AMP-PAN) resin using custom-made sample-loading equipment. It was designed to reduce analytical time and labor with eight peristaltic pumps connected in parallel with eight columns, each packed with AMP-PAN. Eighty liters of seawater containing radiocesium were concentrated to 0.01 L in 6 h with the proposed method and Cs recovery was > 85%. The minimum detectable activity was 0.2 mBq L^–1 at 160,000-s measurement with a high-purity germanium detector.

利用 AMP-PAN 树脂和样品装载设备快速浓缩海水中铯的方法

摘要我们在此介绍一种使用钼磷酸铵-聚丙烯腈（AMP-PAN）树脂浓缩海水中铯的方法，该方法使用定制的样品装载设备。该设备由八台蠕动泵与八根柱子并联而成，每根柱子都装有 AMP-PAN，旨在减少分析时间和人力。使用该方法在 6 小时内将 80 升含铯海水浓缩至 0.01 升，铯的回收率为 85%。使用高纯度锗探测器进行 160,000 秒测量时，可检测到的最小放射性活度为 0.2 mBq L-1。
