Rose Essential Oil Extracted by Supercritical CO_2 Reextraction
利用CO2超临界二次萃取方法提取玫瑰精油
The lower the potential of cathode is, the higher are the rates of U ( VI) reextraction and U ( IV) extraction.
随着阴极电位的降低，U（Ⅵ）反萃和U（Ⅳ）萃取速率均增大。
After reextraction and preconcentration, the rare earth impurities and non-rare earth impurities such as Cu, Pb, Co and Ni in high purity europium oxide are determinated by ICP-AES.
反萃，浓缩后用ICP－AES法测定高纯氧化铕中的稀土杂质和非稀土杂质铜、铅、钴、镍。
Pancreatin concentration in bulk water together with extraction and reextraction phase ratio was optimized by the orthogonal tests, and the results show that the optimum concentration is 1mg/ mL and the optimum phase ratio is 1:1 for both.
正交试验结果表明：本体相浓度、萃取与反萃取相比也影响胰蛋白酶活力，最佳纯化条件是本体相浓度为1mg/mL，萃取与反萃取相比均为1：1。
