本文通過研究hno _ 3 - hf反萃和稀釋有機相後用濃hno _ 3反萃這兩種分離方法,認為hno _ 3 - hf反萃由於在加熱去除hf時酸度不易控制,導致鋯的部分水解,因而此方法不宜用於icp - ms中,然而稀釋有機相後用濃hno _ 3反萃法用於icp - ms測量中,全程回收率為93 . 2 ,相對標準偏差為5 . 24 ,鈾的一次去污因子為3 . 2 10 ~ 4 ,鋯的測定下限為0 . 04ng / ml ,本文首次將tta萃取分離鈾中鋯用於icp - ms測量中,結果令人滿意,此方法適用於快速、準確測量鈾產品中微量鋯。Having compared all separating ways, the authors made a proposal to refine n - heptane and reclaim methylcyclohexane from 120 solvent oil by using composite extraction separation

由於鈾中鋯的含量范圍很廣,從1 . 50 10 ~ ( - 6 ) 3 . 8g / gu ,在分離和測量時,既要考慮盡量地減少鈾的殘留量以消除鈾對鋯測量產生的影響,又要獲得鋯的理想的回收率,因此本文在分離方法的選擇上比較了硅膠吸附分離法, cl - tbp萃取色層法, tta萃取色層法和tta萃取分離法的優缺點,認為tta萃取分離法可以達到理想的分離效果。A quantitative pretreatment scheme suitable to gc - ms analysis of bio - oil was proposed for the first time in china, and an extensive determination of the chemical composition of bio - oil fractions was performed by means of gc - ms coupling. these studies were crucial for the upgrading and utilization of bio - oil. using some novel designing method, which are suitable to biomass and pyrolysis characteristics, were applied in designing the fluid bed biomass flash pyrolysis system
