摘要：

The dynamic interfacial tensions between hydrocarbons and solutions of surfactants having different hydrophilic- lipophilic ability are measured.The effects of ionic strength and alkyl chain carbon- number on dynamic interfacial tensions are also studied.It is found that adsorption- desorption barriers are connected with the hydrophilic- lipophilic ability of surfactants.There exists a large or small adsorption- desorption barrier to the transfer of surfactant having strong hydrophilic or lipophilic ability from water to oil.The influences of ionic strength and alkyl chain carbon- number on adsorption- desorption barriers are discussed.
