Dynamic Surface Tension of Ionic Liquid [C10(EPy)2]Br2 Using Maximum Bubble Pressure Method

The ionic liquids used in this study are (1,1’-decane-1,10-diylbis (3-ethylpyridinium) dibromide. The reason of this experiment is to figure out character of ionic liquids called green solvent. It can help to use of ILs to know that specific feature since ionic liquids are made so many different way. Using maximum bubble pressure method, we tested dynamic surface tension in range of 298K~418K and time range is 0.03s~60s. Among various method of inspecting dynamic surface tension, maximum bubble pressure is the easiest way to have such description of the solution at air/water interface. In the short time, it show only diffusion model, but in the long time range there is different aspect which it called diffusion-controlled model
