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

利用生物样品进行放射剂量评估是估计内部辐射照射的一种有效技术。在这些样本中，尿液是在辐射或核紧急情况下筛选内部辐射照射水平的合适生物材料之一，因为它易于在现场采样。用含阴离子交换基团的多孔聚合物圆盘填料筒将尿样中的铀与矿物成分分离。完成从调节到清洗墨盒所需的时间为20分钟。结果表明，该方法可以简单快速地去除高浓度的矿物成分，同时超痕量的U仍吸附在滤筒上。

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.
