标准范围

该方法通过以下方式进行:测定一系列溶液的表面张力，其浓度包含临界胶束浓度。绘制表面张力图作为浓度对数的函数:临界胶束化浓度对应于该曲线上的奇点。在这一点上，曲线显示出坡度的急剧变化。

The method is carried out in the following way: Determination of the surface tension of a series of solutions whose concentrations bracket the critical micellization concentration. Plotting of the graph of surface tension as a function of the logarithm of the concentration: the critical micellization concentration corresponds to a singular point on this curve. In this point the curve shows a sharp change of slope.
