摘要

Zinc sulfide clusters were synthesized and characterized at low micromolar concentrations to assess the effect of metal- sulfide ligands on metal toxicity to aquatic organisms in oxic environments. Recommended preparation times are greater than 2 h initial reaction of equimolar sodium sulfide and zinc nitrate, followed by oxic aeration for 3 d. Ionic strength, pH, and anoxic stabilization time were found to be relatively unimportant in controlling the final yield. Adsorptive losses of zinc sulfide(ZnS) clusters to surfaces, however, were significant for a variety of vessel materials and membrane filters.
