Abstract: The extraction behaviour of ~(95)Zr with TBP-Kerosene irradiated by variousgamma doses (10~2--10~6Gy) is investigated. The distribution coefficient of ~(95)Zr andretentive percentages of ~(95)Zr in organic phase after scrubbing by 0.01 mol/1 HNO_3and 5% Na_2 CO_3 solution are determined. The TBP-Kerosene used in these tests ispre-equilibrated with various HNO_3 solution(0.5--5 mol/1) before irradiation. Theexperimental results show that the distribution coefficient of ~(95)Zr and retained~(95)Zr in scrubbed organic phase increase as doses and concentration of HNO_3increase. At doses>5×10~4 Gy, the extraction of ~(95)Zr sharply increase with doses.At doses>10~5Gy, ~(95)Zr in the orgenic phase is difficulty stripped by 5% Na_2CO_3solution and emulsion is easily formed. At doses 2×10~6Gy and HNO_3≥3 mol/1,the retentive percentage of ~(95)Zr is >95%. Effect of seven degradation products added to 30% TBP-Kerosene on the extrac-tion and retention of ~(95)Zr are researched. The results indicate that the distributioncoefficients of ~(95)Zr with long chain monoalkylphosphate and hydroxamic acid arelarger than other compounds. When the organic phase is scrubbed with 5%Na_2 CO_3solution, the long chain monoalkylphosphate easily causes emulsion. But thehydroxamic acid is more difficultly scrubbed than long chain monoalkylphosphate by 5% Na_2 CO_3 solution.
