The Effect of pH, Ionic Strength and the Presence of PbII on the Formation of Calcium Carbonate from Homogenous Alkaline Solutions at Room Temperature

Precipitation of calcium carbonates in aqueous systems is an important factor controlling various industrial, biological, and geological processes. In the first part this study, well-known titration approach introduced by Gebauer coworkers 2008 s used to obtain reliable experimental dataset for deep understanding CaCO3 nucleation kinetics supersaturated solutions over a broad range pH ionic strength conditions. second part, effect impurities, i.e., 1 mol% Pb2+, was assessed same Divalent lead has been shown have inhibitory all ranges conditions tested except 8 low (≤0.15 mol/L). Future investigations might take advantage methodology data provided work investigate other system variables. The investigation major variables assessment eventual synergic effects could improve our ability predict formation complex natural systems.
