Figure 8From: Aggregation of montmorillonite and organic matter in aqueous media containing artificial seawaterThe ζ-potential of chitin suspension as a function of pH at three discrete salinity values. At zero salinity, z-potential is a function of pH, with the point of zero charge at approximately pHpzc = 5.5. However, when a small amount of electrolyte is present in the system, ζ-potential immediately becomes insensitive to pH, with its value very close to zero.Back to article page
