通过使用改进的磁泳观察装置，测量了包含月桂酸的2-氟甲苯液滴在镝(III)水溶液中的磁泳速度。纯2-氟甲苯液滴的磁泳速度与半径的平方成正比。另一方面，镝(III)溶液中包含月桂酸的有机液滴的速度显示出与半径平方关系的偏差，在半径小于2μm的较小液滴中更为明显。这些结果表明镝(III)-月桂酸盐络合物是在液-液界面形成的。本研究是首次通过微滴磁泳检测界面复合物的报道。
By using an improved apparatus for the observation of magnetophoresis, the magnetophoretic velocity of 2-fluorotoluene droplets including lauric acid was measured in aqueous dysprosium(III) solution. The magnetophoretic velocity of pure 2-fluorotoluene droplets was proportional to the square of the radius. On the other hand, the velocity of the organic droplets including lauric acid in the dysprosium(III) solution showed a deviation from the square radius relationship, more remarkably in smaller droplets than 2 μm in radius. These results indicated that the dysprosium(III)–laurate complex was formed at the liquid–liquid interface. This study is the first report on the detection of the interfacial complex by the magnetophoresis of the microdroplet.
