Zeta potential is a measure of the electrostatic potential at the interface between a solid particle and a surrounding liquid, commonly used to characterize the stability of colloidal suspensions. Zeta potential is significant in sedimentology, soil science, and environmental chemistry for understanding the behavior of fine particles, the aggregation of sediments, and the transport of contaminants in natural waters.
