文章研究了处理50μg~(252)Cf中子源的工艺条件。其中包括,不锈钢外壳和Pd-Cf_2O_3陶瓷体的化学溶解;蒸馏除Cl~-;50%TBP单级萃取Cf和Cm;螯合树脂EDTA(D 401)吸附Pd和1-甲基庚基苯膦酸(P 5706)萃取色层分离Cf和Cm。根据研究的工艺条件,给出了处理~(252)Cf中子源的工艺流程,可在一个热室中完成。Cf的回收率大于90%;Cf和Fe,Pd能达到满意的分离。
The article studied the processing conditions of 50μg ~ (252) Cf neutron source. Including the chemical dissolution of stainless steel shell and Pd-Cf 2 O 3 ceramic body; the removal of Cl ~ - by distillation; the extraction of Cf and Cm by single stage with 50% TBP; the adsorption of Pd and 1-methylheptylphenylphosphine by EDTA (D 401) Acid (P 5706) Extraction Chromatography Cf and Cm. According to the research process conditions, the process flow of ~ (252) Cf neutron source is given and can be completed in a hot chamber. Cf recovery rate greater than 90%; Cf and Fe, Pd can achieve satisfactory separation.
