Finally glycyrrhiza as the raw material were extracted by the aqueous two - phase . the influences of the extraction time , temperature , the extractant ration ( filtrate / extractant ) , quantity ration were studied . the optimum condition was also determined 最后以甘草為原料，用雙水相萃取技術提取甘草酸，對于不同分子量的聚乙二醇peg ，考察了提取時間、溫度、萃取劑比例(濾液萃取劑)和雙水相組分比聚乙二醇與硫酸銨質量比[ peg ( nh ) 4so4 ]對萃取量的影響，從而確定它們的最佳工藝條件。 |

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。 |

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 镎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于95的镎趕入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，錒系的回收率大于99 . 99 ，并且基本上實現了錒鑭元素的組分離。其要點如下： 1 |
