摘要：
Surface tension is one of the main physical parameters of foams. The surface tension of Sodium Dodecyl Benzene Sulfonate (SDBS) solution and Triton solution are measured by the drop volume method, and the CO2 saturated SDBS solution is also measured in this paper. It is found the solution concentration has an obvious effect on the surface tension. For SDBS solution, the surface tension gradually decreases with the increase of surfactant concentration while keeps constant after a certain concentration. For Triton solution, on the other hand, the surface tension always remains approximately constant in the studied concentration region. The surface tension of CO2 saturated SDBS solution is slightly higher than SDBS solution through experimental investigations.
