Adsorption of radionuclides in no-carrier-added (NCA) amounts from liquid metals оf Rb, Pb, and Ag was investigated. ⁸²Sr may be recovered from metallic irradiated Rb-target via adsorption onto various surfaces. A high chemical yield is achieved at Sr-sorption from molten Rb of big mass directly onto the inner surface of the target shell at about 300 °C. The investigation showed that the formation and dissolution of oxide sol particles of rubidium oxide, where ⁸²Sr is initially adsorbed in SrO form, play an important role in the mechanism of adsorption. The approach is prospective for different modes in “off-line” and “on-line” ⁸²Sr production. Direct sorption of different NCA radionuclides from molten Pb and Ag was also investigated. Chemical nature of the surface (Ta, Ni, Ti, Mo, Al, or quartz) is very critical for sorption of ^188,189Ir, ¹⁸⁸Pt,¹⁹⁸Au,⁹⁷Ru,¹⁸⁵Os,^182mRe,⁹⁹Mo and ^99mTc from molten Pb, and for sorption of ¹⁰⁰Pd,^101mRh,⁹⁷Ru, ⁹⁶Tc from molten Ag.

从液态金属中吸附：从辐照靶中回收放射性核素的方法

研究了Rb，Pb和Ag中液态金属对无核素（NCA）中放射性核素的吸附量。⁸²由金属通过吸附照射的Rb-目标在各种表面上的Sr可以被回收。在约300°C的温度下，从大质量的熔融Rb直接吸附到目标壳的内表面时，Sr吸附可实现很高的化学收率。研究表明，最初以SrO形式吸附⁸² Sr的氧化rub的氧化物溶胶颗粒的形成和溶解在吸附机理中起着重要作用。该方法适用于“离线”和“在线”的不同模式⁸²高级生产。还研究了从熔融的铅和银中直接吸附不同的NCA放射性核素。表面的化学性质（Ta，Ni，Ti，Mo，Al或石英）对于从熔融液中吸附^188,189 Ir，¹⁸⁸ Pt，¹⁹⁸ Au，⁹⁷ Ru，¹⁸⁵ Os，^182m Re，⁹⁹ Mo和^99m Tc至关重要Pb，用于从熔融的Ag中吸附¹⁰⁰ Pd，^101m Rh，⁹⁷ Ru，⁹⁶ Tc。
