本文研究用TBP-聚四氟乙烯反相分配色层分离法制取无载体~(111)Ag_0采用盐酸体系低酸度下吸附银、高酸度下解吸,获得满意结果。 制备方法:称取相当于250mgPd的氯化钯,密封于石英安瓿中,在原子能研究所反应堆中辐照;热中子通量1×10~(13)n/cm~2·s,辐照68小时,冷却25天后打开石英安瓿,用1N HCl溶解,取相当于50mgPd的溶液,小心蒸发至干,并用0.075N HCl溶解、稀释至10ml,在
In this paper, TBP-polytetrafluoroethylene reversed phase partition chromatography was used to prepare carrier-free (111) Ag_0. Hydrochloric acid was used to adsorb silver with low acidity and desorbed with high acidity. Satisfactory results were obtained. Preparation: Weigh equivalent to 250mgPd of palladium chloride, sealed in a quartz ampoule, in the Institute of Atomic Energy irradiation reactor; thermal neutron flux 1 × 10 ~ (13) n / cm ~ 2 · s, irradiation 68 hours. After cooling for 25 days, open a quartz ampoule, dissolve with 1 N HCl, take a solution equivalent to 50 mg Pd, carefully evaporate to dryness and dissolve with 0.075 N HCl, dilute to 10 ml,
