5) four-step extraction
四步提取法
1.
Methods and Results: Details of the "four-step extraction" of in-gel digestion were discussed in this paper.
方法:将改进的胶内酶切“四步提取法”,应用到96个双向电泳蛋白质斑点分析。
6) sequential extraction method
逐步提取法
1.
The soil polluted by heavy-metal was selected as the soil samples and added NaOH solution,CaO solid,Na2S solution,Na2CO3 solid, C9H7NO solution,and different chemical forms of Pb were extracted with sequential extraction method.
以被重金属污染的农田土壤为样品,分别加入NaOH溶液、CaO固体、Na2S溶液、Na2CO3固体、C9H7NO溶液作为改良剂,采用逐步提取法对土壤中重金属Pb的相态进行浸提和萃取,采用原子吸收光谱法测定提取液中每种形态铅的浓度;最后分析了土壤中Pb在不同的实验环境下的含量。
补充资料:分步结晶
一种古老的用于分离化学性质相近的金属化合物的方法。此法依靠化合物间溶解度的微小差别,通过重复操作而达到分离的目的。钽、铌复合氟化物(如K2TaF7和K2NbOF5·H2O)的分步结晶,锆、铪复合氟化物(如K2ZrF6和K2HfF6)的分步结晶,铷、钾草酸盐的分步结晶,轻稀土硝酸盐和硝酸铵(或硝酸镁)复盐的分步结晶等,都曾经在工业上应用。此法近年来虽然多被溶剂萃取法和离子交换法所代替,但在某些条件下仍然应用。
