水/油界面的表征因其与化学、生物学和技术的各个领域的相关性而成为许多研究的主题。目前许多小组正在研究水/油界面的界面行为的某些方面。然而，大多数实验都存在所用化合物纯度不够的问题。要了解潜在的界面过程，首先需要获得有关所应用的表面活性剂吸附性能的可靠数据。然而，这些只能从可靠的实验中获得。近年来，两亲物在空气/水界面吸附特性的表征取得了长足的进展，这主要归功于表面化学研究的实验边界条件的改进。它们涉及（i）修改表面活性剂溶液表面张力测量的实验条件，以获得准确的值，1、2（ii）应用标准来判断“表面化学纯度”的必要和充分等级，3、4和（iii）获得该纯度等级的有效方法。 5, 6 这与表面状态方程的新方法一起揭示了许多新颖的吸附特征。 7-11
The characterization of the water/oil interface is the subject of many investigations because of its relevance in various areas of chemistry, biology, and technology. Many groups are currently investigating certain aspects of the interfacial behavior of the water/oil interface. However, most experiments suffer from a lack of purity of the compounds used. To understand the underlying interfacial processes necessitates first of all to have available reliable data on the applied surfactants’ adsorption properties. These, however, can only be obtained from reliable experiments.In recent years there has been considerable progress in the characterization of the amphiphiles’ adsorption properties at the air/water interface which is mainly due to improvements in the experimental boundary conditions for research in surface chemistry. They refer to (i) modifications on the experimental conditions on the surfactant solutions’ surface tension measurement in order to get accurate values, 1, 2 (ii) the application of criteria to judge the necessary and sufficient grade of “surfacechemical purity”, 3, 4 and (iii) efficient methods to obtain this grade of purity. 5, 6 This together with a new approach to the surface equation of state has revealed a lot of novel adsorption features. 7-11
