錒系元素
英文
actinide elements-
Studies of amido podands on extractive behaviour of lanthanide and actini des
酰胺莢醚對鑭系和錒系元素萃取性能的研究The path - way controlling of neptunium in co - decontamination step of purex process, the extraction thermodynamics of amido podand and its usage in recovery of actinides from simulated hllw have been investigated. more than 95 % np were maintained in np ( v ) in 1a extractor and flowed into 1 aw, if enough amount of hno2 was added in feed adjustment and then hno2 scavenger ( urea ) was added before extraction. three kinds of amido podand were synthesized, and the extraction of lanthanides, actinides and some fission products were studied. one of them ( tbopda, n, n, n ', n " - tetrabutyl - 3 - oxa - pantenadiamide ) was used as extractant to recover actinides from hllw. the results of experiments show that more than 99. 99 % actinides were recovered from hllw and separated basically in groups. the main digests are as follows : 1
鎿走向控制研究中通過調價階段加入亞硝酸、而萃取前清除亞硝酸的獨特辦法可以將大於95的鎿趕入1aw 。合成了三種酰胺莢醚萃取劑，研究了它們對錒系和裂片元素的萃取熱力學，通過條件實驗選擇了其中一種莢醚tbopda （ n ， n ， n 』 ， n 』 ?四丁基? 3 ?氧戊二酰胺） ，進行了從模擬高放廢液中分離錒鑭系元素的工藝研究，錒系的回收率大於99 . 99 ，並且基本上實現了錒鑭元素的組分離。其要點如下： 1Nuclear criticality control of special actinide elements
