Abstract HEEP COPYRIGHT: BIOL ABS. A study was conducted to determine the hydroxide solubility for Zn, N, Cd and Pb over a range of approximately pH 6-13; the determination of carbonate solubility for the same heavy metals over the same pH range, at selected carbonate, concentrations; and a comparison of the residual soluble metal in the hydroxide system with that in the carbonate system. Hydroxide solubility can be predicted for Cd and Pb from published solubility constant values, and for Zn and Ni based upon experimental determined values presented. Solubility cannot be predicted based on equilibrium conditions for the carbonate system, and the kinetics of precipitation appear such for Zn and Ni that the carbonate form of these metals will not form within typical treatment plant detention times.
