中性磷型萃取剂对铀或钚均有较好的萃取选择性,它们可用于铀的纯化、裂变产物分离及热铀处理等工艺,其中磷酸三丁酯是目前最常用之磷型萃取剂,无论是新萃取剂的萃取性能测试,或是它们的化学稳定性及耐辐射性能的测定工作都以磷酸三丁酯为标准进行比较。关于磷酸三丁酯的辐解研究虽已有报道,但由于辐解工作系在不同之实验条件下(例如射线种类、照射之剂量及剂量率、辐射样品之来源及其纯化方法等等不同)进行,而且样品在电子射线作用下吸收剂量之计算方法、各种辐解气体及液体产物之分析方法也不相同,故文献上报道之辐解结果亦不一致。
Neutral phosphorous extractant has good extraction selectivity for uranium or plutonium, which can be used for uranium purification, fission product separation and heat uranium treatment process, of which tributyl phosphate is the most commonly used phosphorus extractant , Whether it is the extraction performance of the new extractants, or their chemical stability and the determination of radiation resistance are compared with tributyl phosphate as a standard. Radiation studies on tributyl phosphate have been reported, however, since radiolysis is carried out under different experimental conditions (for example, the type of radiation, the dose and dose rate of irradiation, the source of the irradiated sample, the method of its purification, etc.) , And the calculation method of the absorbed dose of the sample under the action of the electron ray is also different from that of the method of analyzing various radiolysis gases and liquid products. Therefore, the radiolysis results reported in the literature are also inconsistent.
