| 摘 要： | 采用系列相比法研究了吸收剂量、辐照前预平衡硝酸浓度、辐照前体系中含钌、萃取水相的硝酸浓度等对钌保留的影响,并测定了几种模拟辐解产物对钌的萃取.结果表明,γ辐照后的TBP-正十二烷萃取钌达平衡很慢,碱洗涤平衡较快；随着吸收剂量、辐照前预平衡硝酸浓度、循环使用次数的增加,钌保留增加；辐照前体系中含钌时,则钌保留较大；含钌的...

| Abstract: | The retention of the nitrato complexes of nitrosylruthenium by the irradiated TBP-n-dodecane-HNO3 is studied.The extraction equilibrium time of the nitrato complex of nitrosylruthenium by the irradiated TBP-n-dodecane-HNO3 and the washing equilibrium time by sodium carbonate were determined.The distribution coefficients of ruthenium by several model radiolysis products were determined.The effects of absorbed dose,the nitric acid concentration of the nitrosylruthenium nitrato complex,the nitric acid concentr... |
