Abstract
Measurements of low-level dissolved-sulfide concentrations in estuarine water from San Francisco Bay have been made using the sulfide-specific electrode after preservation, separation, and preconcentration of the sulfide species. The separation and preconcentration were acheived by coprecipitation of ZnS with Zn(OH)2 followed by collection and dissolution of the precipitate, giving concentration factors up to 160-fold Preconcentration provided sulfide solutions that were adequately measurable within the practical working range of the specific-ion electrode The sulfide detection limit with the preconcentration step is 0 02 ??g/l Spike recoveries in the range of 81 to 10 1% have been achieved for laboratory-prepared samples having S2- concentrations as low as 0 6 ??g/l and 84 to 100% for an estuarine sample spiked in the field with 2 ??g/l (S(-II) Positive correlations have been found between dissolved S(-II) concentrations and concentrations of dissolved Cd, Cu, and Ni, negative correlations have been found between bisulfide (HS-) activity and activities of Cd2+, Cu2+, and Ag+ species ?? 1984 Springer-Verlag New York Inc.
