Abstract

The invention discloses a dynamic method for measuring surface property parameters of a substance. In the dynamic method, the surface property parameters of a liquid substance to be measured are obtained by processing the substance to be measured by electrolyte solution, measuring the activity of the liquid to be measured after reaction according to a set time interval and carrying out processingby a dynamic data processor and a surface property operation module in a detection system. According to the dynamic method, the ion exchange dynamic method is adopted to overcome the difficulties that in the measuring process, the reaction balance time is long, the balance is difficult to determine and the accurate calibration of an m value is difficult to implement; dynamic data obtained in short time is utilized to carry out accurate forecasting, so that the difficulties that the balance time is long and the balance is difficult to determine are overcome; five parameters of surface properties of the substance can be calculated only by two parameters, i.e. the intercept and the slope, of an equation of linear regression, which is obtained by the dynamic data; and meanwhile, after the dynamic method is adopted, the total quantity of surface charges can be directly measured.
