  12. 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： 1
  13. The method of concentrating the decoloration solution of tylosin is usually carried out by thin film vacuum concentration. in this experiment, the concentration process is modified by using the nanofiltration membrane technique which is free from corrosive due to the extractant solvent and in the same time, heating and decomposition of the antibiotic are eliminated, the concentration course ia also distinctly shortened. in this process the small molecule can be filtered by water, and the quality of the product such as, the tyramine content, the solubility of the product, improved significantly. in addition, the membrane filtration process could save consumption of steam and cooling water

    泰樂星提煉過程中原工藝脫色液用薄膜真空濃縮，本試驗改進為耐溶媒納濾膜濃縮，料液不需要加熱即可濃縮，防止了料液的高溫分解破壞，濃縮收率明顯提高在濃縮的同時，部分小分子雜質可以隨水分子一起通過納濾膜而除掉，成品質量明顯提高，解決了用原工藝成品酪胺、溶解度不合格的質量問題省去了原工藝濃縮中費用較高的蒸汽、冰鹽水，經濟效益可觀。
