采用多孔高硅氧玻璃作吸附柱，研究了在8mol/LHNO3介质中237Np与子体233Pa的分离和测定。研究结果表明，用H2SO4解吸233Pa，能使237Np与233Pa定量分离。237Np和233Pa的放化回收率分别为99％～101％和99％～103％，方法的相对标准偏差分别为2％和3％。

채용다공고규양파리작흡부주，연구료재8mol/LHNO3개질중237Np여자체233Pa적분리화측정。연구결과표명，용H2SO4해흡233Pa，능사237Np여233Pa정량분리。237Np화233Pa적방화회수솔분별위99％～101％화99％～103％，방법적상대표준편차분별위2％화3％。
The separation and determination method of 233Pa and 237Np isstudied. 233Pa is quantitatively adsorbed by Vycor glass column from 8 mol/L HNO3 solution containing 237Np-233Pa. Subsequently, 233Pa is eluted from the Vycor glass column with concentrated H2SO4 solutiion and Np and Pa is completely separated. Then α-radioactivity of 237Np and γ-radioactivity of 233Pa are measured with liquid scintillation counting method and γ-energy spectrum method separately. The precision of the method is: 2 % for 237Np, 3 % for 233Pa, the recovery of added standard radioactive samples is: 99 %～101 % for 237Np, 99 %～103 % for 233Pa.
