A competitive ligand equilibration/solvent extraction (CLE/SE) technique was used to examine silver complexation in the particulate, colloidal, and dissolved states of wastewater effluent and receiving waters. Additions of silver at near ambient leve

Silver, inorganic sulfide, and thiol compounds were measured in municipal wastewater effluent, receiving waters, and pore waters from an anoxic lake sediment in order to predict silver speciation in these systems. The authors found submicromolar conc

Speciation determinations involve uncertainty in system definition and experimentation. Identification of appropriate metals and ligands from basic chemical principles, analytical window considerations, types of species and checking for consistency i

Formation constants for silver thiolates were obtained by titration of the ligand in a constant temperature, ionic strength and pH medium and measuring the potential change at a Ag2S electrode. A non-linear equation was derived from which the first a

Dissolved silver (Ag) in the presence of amorphous iron sulfide(FeS) rapidly equilibrates to ultra-trace levels ( ∼5 ng/L), which agrees with equilibrium calculations based on Ag2S solubility. This finding, along with the authors' discovery that cr
