Zeta potential measurements provide for a unique method to quantify the actualstate of the solid to solution interface in situ. In this study, zeta potentials for syntheticand biogenic calcium carbonate suspensions prepared in 1mM NaCl at different pH weremeasured. Also, in forming calcite crystals with macromolecules as an additive extractedfrom oyster shell, the zeta potentials were measured. These studies were performed toverify the primary role of macromolecules in controlling the formation, morphologicaldevelopment and crystallography of the biocomposite. Also, a new model of the electricalpotential model of the composite interface region is proposed to evaluate effective zetapotentials.
