In the previous report, the authors determined the interfacial tension between liquid sulfur and water. It was also observed previously that the surface active agent improved the extraction of sulfur from ore in an autoclaving method. From this point of view, the authors measured the interfacial tension between liquid sulfur and water containing small quantities of surface active agent. Two anionic agents of ester of sodium lauryl sulfate and sodium alkylnaphthalensulfonate, and non-ionic agent of polyoxyethylen solbitan oleate were used. The experimental results showed that an abrupt change in the interfacial tension corresponded to the characteristic concentration of agent. This fact was considered to be comparable to critical micelle concentration of the surface active agent.
