Abstract

The invention discloses a system for measuring and analyzing parameters of a surface property of a material based on a dynamic method. The system comprises a sample processing system and a measuring system; a to-be-measured material is processed with an electrolyte solution; the activity of to-be-measured liquid after reacting is measured at a preset time interval; and a dynamic data processor and a surface property calculating module in the measuring system are used for processing the to-be-measured liquid material, thereby obtaining the parameters of the surface property of the to-be-measured liquid material. An ion exchange dynamic method is used for overcoming the defects of long reaction balancing time, difficulty in confirming balance and difficulty in realizing accurate calibration of an m value during a measuring process; dynamic data acquired within a short period of time can be used for accurate forecast so as to overcome the problems of long balancing time and difficulty in confirming balance; only two parameters, namely intercept and gradient in a linear regression equation obtained through the dynamic data, are used for calculating five parameters of the surface property of the material; and the total amount of the surface charges can be directly measured.

Description
