Sažetak
The natural “complexing capacity” of aquatic systems was determined using titration with cupric ions. It was compared with “complexing capacity” determined in the presence of both EDTA, used as a model for organic substances, and of EDTA and γ- Al2O3. The γ-Al2O3 was used as a model for solid particles of hydrous oxide in natural waters. The adsorption isotherm of copper in seawater on γ- Al2O3 particles was determined with and without EDTA. For EDTA alone and for the Cu—EDTA complex, it was found that they are not adsorbed on γ-Al2O3 in the natural seawater. However, by adsorption on solid particles, the labile ionic Cu-complex can be removed from the seawater.
