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 microm 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.
通过使用一种改进的磁泳观测装置，在水溶液中镝（III）溶液中测量了含月桂酸的2-氟甲苯液滴的磁泳速度。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，在镝（III）溶液中含月桂酸的有机液滴的速度偏离了与半径平方的关系，在半径小于2微米的较小液滴中更为明显。这些结果表明，在液-液界面形成了镝（III）-月桂酸络合物。本研究是关于通过微滴磁泳检测界面络合物的首次报道。
