  4. 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

    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
  5. The adsorption isotherm of neptunium on silica gel correspond to the form of langmuir isotherm. according to clausius - claperon equation, from the slope in inkd vs 1 / t plot, adsorption heat could be estimated. from the data of adsorption heat it is concluded that the adsorption of neptunium on silica gel in nitric acid solutions belongs to chemical adsorption and the adsorption process is an endothermic reaction

    三種價態的在硅膠上吸附的等溫線符合蘭格繆爾吸附等溫線的形式,是單分子層吸附;根據克勞修斯-克拉柏龍方程,以1nkd對1 t作圖,通過直線斜率計算出吸附熱,從吸附熱的數據可判斷三種價態的在硅膠上的吸附屬于化學吸附,是吸熱的過程;對npov ) 、 np ( v )和np ( vd在硅膠上的吸附進行了比較,提出了三種價態的鋒在硅膠上吸附的機理。
  6. Adsorption distribution coefficients increase with the increasing of temperature. the concentrations of redox reagents have light effects on adsorption within the studied concentration range

    測定了硝酸溶液中三種價態的在硅膠上吸附的等溫線和表觀吸附熱。
