| 摘 要： | 一、前言用阳离子交换-α-HIBA淋洗色层分离Am,Cm时,Pm在Am.Cm之间被洗脱。前文研究了用DTPA-α-HIBA从Am.Cm中除Pm的可能性。本文的目的是研究在阳离子交换树脂-DTPA-乳酸体系中,各种因素对Am,Cm和Pm分离的影响,以寻找从Am,Cm中除Pm的条件。

| Abstract: | The effect of various factors on the separation of Am and Cm from Pm inthe cation exchange-DTPA-lactic acid system is studied, such as the concentra-tion of DTPA, pH of the eluant, temperature and flow rate. Separation results show that the recovery of Am and Cm is 99.18% and thedecontamination factor of Am, Cm from Pm is 431. |
