Because the concentration of zirconium in uranium has large ranges, from 1. 50xlo ' 6 - 3. 8g / gu, not only how to decrease the remainder of uranium to eliminate its determinate effect but also how to acquire higher recovery of zirconium is considered, so the method of silica gel, the method of tbp levextrel resin chromatography, the method of tta chromatography and the method of tta extraction are compared. then tta extraction is chosen to acquire the ideal separation purpose. compared with icp - ms and icp - aes, xrf has characters of high repeatability, stability, low cost, high concentration elements analysis, the ability to determinate solid sample and having comprehensive practicability, but xrf has lower sensitivity, so how to increase the concentration of the sample to acquire better precision is a difficult problem, the optimum of operating condition : the integral time of spectral lines is 60s, the integral time of background lines is 20s, the voltage of xrf is 50kv, the electric current is 50ma
由於鈾中鋯的含量范圍很廣，從1 . 50 10 ~ （ - 6 ） 3 . 8g / gu ，在分離和測量時，既要考慮盡量地減少鈾的殘留量以消除鈾對鋯測量產生的影響，又要獲得鋯的理想的回收率，因此本文在分離方法的選擇上比較了硅膠吸附分離法， cl - tbp萃取色層法， tta萃取色層法和tta萃取分離法的優缺點，認為tta萃取分離法可以達到理想的分離效果。 -
