Organic compound-exclusion adsorbent for rapid measurement of U in urine sample

使用生物样本进行放射剂量评估是估算内照射剂量的有效方法。在这些样本中，尿液是筛选辐射或核紧急情况下内辐射暴露水平的合适生物材料之一，因为它可以很容易地在野外采样。使用含有阴离子交换基团的多孔聚合物圆盘填充柱将尿样中的铀与矿物成分分离。完成从调理到清洗墨盒的过程所需的时间为20分钟。对高浓度的矿物组分进行了简单、快速的去除，而超痕量的铀仍被吸附在滤柱上。

Radiological dose assessment using a biological sample is an effective technique for estimating internal radiation exposure. Among such samples, urine is one of the suitable biological materials for screening the level of internal radiation exposure during radiation or nuclear emergencies, because it can be easily sampled in the field. Uranium in a urine sample was separated from mineral components using anion exchange group-containing porous-polymeric-disk-packed cartridge. The time required to accomplish the procedure from conditioning to washing of the cartridge was 20 minutes. A simple and rapid removal of mineral components with high concentrations was demonstrated, while the ultratrace amount of U remained adsorbed on the cartridge.
