摘要
以活性Al2 O3为吸附剂 ,采用吸附型大体积水样采集装置浓集水中钚 ,用HNO3 NaF溶液浸出钚 ,最后分离纯化。在 10 0L自来水中加入 5 0× 10 - 3 Bq/L2 39Pu时 ,全程放化回收率为 :(4 7 6± 8 5 ) % ,10 0L水中2 39Pu的探测下限为 3 0× 10 -
The adsorption type sampling is used to concentrate plutonium from large volume of water. Neutral Al 2O 3 is activated and acts as adsorbent. Plutonium is leached by HNO 3 NaF, then seperating and sublimating procedures are performed. The radiochemical recovery is found to be (47.6±8.5) % and the detection lower limit is 3.0×10 -6 Bq/L(100 L water).
