| Abstract |
A pH-dependent, continuous, multiligand model is described. It is based on the Gaussian distribution model, which has been used to describe both binding by humic substances as well as metal binding by humic substances. However, the Gaussian distribution model has never been used to describe the competitive binding of the metalated and protonated ligand species. The inclusion of pH dependence should allow one to predict metal binding constants that are more representative of true thermodynamic binding constant rather than curve-fitting parameters with no chemical significance.
