Abstract
A system and process for determining and analyzing surface property parameters of a substance based on kinetic method is provided. The system comprises a sample processing system and a detection system. The sample processing system includes a reactor (3), a collector for liquid to be tested (5), and a container for liquid to be tested (6). The detection system includes a detecting electrode (13), a concentration and activity operator, a kinetic data processor, a surface property operation module, and a result output module. The process comprises: having the substance to be tested to be treated with an electrolyte solution, measuring activity of liquid to be tested upon reaction at a pre-set time interval, and processing with the kinetic data processor and the surface property operation module, so as to obtain surface property parameters of the substance to be tested. The present invention adopts kinetic method of ion exchange to overcome the issues associated with long reaction equilibrium time, not easy to determine equilibrium and not easy to accurately determine the value of m. Five parameters of the substance surface property can be calculated with only intercept and gradient of the linear regression equation obtained from the kinetic data, and the total amount of surface charge can also be directly determined.
