摘要
文章介绍了用CL-5209萃淋树脂分离铀、二安替比林甲烷光度法测定八氧化三铀中微量钛的方法研究。该法选择性高、形成的络合物稳定性好。方法的相对标准偏差为±3%,回收率为100～104%。在含0～20μg钛的范围内,服从朗伯-比耳定律。
In the paper a spectrophotemetric methed for determination of mieroamountof titanium in uranium oxide with diantipyrylmethane is described. The titaniumis preseparated from uranium using CL-5209 solvent-containing resin. The ?mplexformed is very stable. Eeer's law is obeyed over the range 0--20 μg Ti/25ml.The recovery of this method is 100～104% and the relative standard deviation is±3%. This method is simple, rapid and selective, and it is now used as a routinemethod for titanium determination in uranium oxide.
