Abstract |
Experiments were conducted to study the effect of a pH > or = 9.0 and a low total inorganic carbonate (TIC) concentration of 10 to 80 mg as CaCO3/L on lead solubility. The results were compared with those of earlier experiments in which the pH was 8.0 to 8.5. In the experiments that had pH's > or = 9.0, lead leaching was reduced, as was consumption of both residual free chlorine and dissolved oxygen. The results closely followed the predictions of a solubility model that allowed for aqueous lead complexation and control by the solid basic lead carbonate under the experimental pH and TIC conditions. |
