摘要：

The potential for silver to be strongly bound by organic ligands in marine waters has been examined using a new competitive equilibration/solvent extraction technique, The method is based upon establishing a competition for silver between ligands already present in the sample acid added diethyldithiocarbamate in chloroform, The final distribution of the metal is measured by graphite furnace atomic absorption spectroscopy. Analyses of samples from the Weddell Sea and the San Francisco Bay gave no evidence of any significant silver-organic complexation, indicating that the chemical speciation of silver in seawater is dominated by inorganic chloride complexes.
