ZETA-POTENTIAL MEASURING METHOD AND ZETA-POTENTIAL MEASURING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a zeta-potential measuring method and a zeta-potential measuring system to simply obtain zeta-potential for each particle size of particles.

SOLUTION: A zeta-potential measuring method includes the steps of measuring temporal change of parameters related to stress at a position in a suspension liquid including particles while applying electric field to the suspension liquid, and calculating zeta-potential for each particle size of particles by using the temporal change of the parameters and particle size distribution of the particles.
