本文用萃取光度法研究了Th(IV)-8-羟基喹啉-乙基紫离子缔合体系的显色反应,提出了一个新的高灵敏的测定痕最钍的显色体系,探讨了缔合物的形成条件,并进行了合成试样中钍的测定。
In this paper, the color reaction of Th (IV) -8-hydroxyquinoline-ethyl violet ion association system was studied by extraction spectrophotometry. A new highly sensitive colorimetric system for the determination of trace thorium was proposed. The conditions for the formation of the compound were determined and the determination of thorium in the synthesized sample was carried out.
