[求助] Zeta点位能说明什么

看文献测粒径,一般都要测zeta点位,却不知道zeta点位能代表什么,有木有大侠指点一下?

The direct information you can get is their surface charge state (negatively, neutral, or positively charged). Moreover, you can judge the colloidal stability of these particles from these data. Usually particles with a zeta potential more negative than -30 mV or more positive than +30 mV are considered a stable system.
