Abstract

The equilibrium distribution of a given metal ion or ligant among free, complexed and solid-phase forms in a particular system depends strongly on pH, p epsilon (redox potential), the total concentrations of all system ligands, and the total concentration of all system metals. Computations for fairly complex model natural water systems are presented. the computatins illustrate the combined influences of acid-base, complexation, redox, and dissolution-precipitation reactions on metal speciation. A simplified three-compartment model is employed in the computations to simulate the distinctive characteristics (essentially p epsilon and pH) of well-oxygenated epilimnetic waters, hypolimnetic waters, and reducing sediments with respect to metal-ion and ligand distributions.
