摘要：
Surface tensions of solutions of sodium, potassium and ammonium persulphates in water and warer + acetone( X-acetone = 0.016, 0.033, 0.072 and 0.117) mixtures have been measured by means of the ring detachment method at 298.15, 303.15, 308.15 and 313.15 K. The data were analyzed using the Gibbs equation and various thermodynamic functions have been evaluated. The results reveal the nature of solute adsorption at the interface in these solutions.
