采用多孔高硅氧玻璃作吸附柱 ,研究了在 8mol/LHNO3介质中2 37Np与子体2 33Pa的分离和测定。研究结果表明 ,用H2 SO4 解吸2 33Pa ,能使2 37Np与2 33Pa定量分离。2 37Np和2 33Pa的放化回收率分别为 99%～ 10 1%和 99%～ 10 3% ,方法的相对标准偏差分别为 2 %和 3%
Using porous silica glass as adsorption column, the separation and determination of 2 37Np and 2 33Pa in 8mol / L HNO3 media were studied. The results show that the desorption of 2 33 Pa with H2 SO4 can separate 2 37Np and 2 33Pa quantitatively. The radiochemical recoveries of 2 37Np and 2 33Pa were 99% -101% and 99% -103%, respectively. The relative standard deviations of the method were 2% and 3%
