详细
The dependence of interfacial tension on the temperature and concentration of surfactant (stearic acid) in a water–n-heptane system is investigated. Studies are performed in the temperature range from room temperature to 100°C without the surfactant and at four different concentrations of it. The dependence of the excess surface chemical potential of stearic acid molecules on temperature and concentration is determined, based on the experimental results.
