本文用萃取光度法研究了UO_2~(2+)-吡啶-3-甲酸-乙基紫离子缔合体系的显色反应,提出了用苯:MIBK(3:1)作为萃取剂的一个高灵敏度的显色休系,探讨了萃取比色的最佳条件,并进行了合成试样中铀的测定。
In this paper, the color reaction of UO_2 ~ (2 +) - pyridine-3-carboxylic acid-ethyl violet ion association system was studied by extraction spectrophotometry. A high sensitivity of benzene: MIBK (3: 1) Of the color off rest, to explore the best extraction colorimetric conditions, and the determination of uranium in the synthetic samples.
