CL-5209 SOLVFNT-CONTAINING RESIN PRESE-PARATION AND SPECTROPHOTOMETRIC DETERMINATION OF MICROAMOUNT OF TITANIUM IN URANIUM OXIDE

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.
