Is the surface charge of the adsorbent always the same sign as the zetta potential in a system?

When the pH of the solution is below the isoelectric point the surface charge of the solid adsorbent becomes positive. Does this mean that the zetta potential will also be positive? or Is the zetta potential always the same sign as the surface charge in a solid-liquid system?

Kaushik Pal

yeah it means the surface charge is positive.
