本工作自行设计和工了一套高压排空离子色谱柱系统。利用该系统建立了样品中同时分离Np和Pu的阴离子交换色谱分离方法,并将其用于1AW中同时分离镎和钚,取得了良好效果。利用氨基磺酸亚铁和盐酸羟胺将样品溶液中的镎和钚的价态同时调整为4价并将底液调整为7.6mol/L HNO3后上柱, This work designed and built a set of high pressure exhaust ion chromatography system. The system was used to establish an anion exchange chromatographic separation method for simultaneous separation of Np and Pu in the sample. The separation method was applied to the simultaneous separation of 镎 and plutonium in 1AW, and achieved good results. The use of iron sulfamate and hydroxylamine hydrochloride sample solution 镎 and plutonium valence simultaneously adjusted to 4 valences and the bottom liquid was adjusted to 7.6mol / L HNO3 on the column,
