Sažetak
The adsorption on solid particles of natural organic ligand in seawater of Cu(II) ions, and of the inert Cu(II) complexes has been studied. Model solids, γ-Al2O3, Na+-0.392-γ-Al2O3, ‘Aerosil 200’, chrysotile, northupite and CaCO3 were added to seawater. It was observed that at pH 8 natural organic matter was strongly adsorbed on chrysotile and was not adsorbed on Na+ -0.392-γ-Al2O3 ; it was also adsorbed on γ-Al2O3 over the range of 3 < pH < 7. In this pH range, the complexing capacity and adsorption of Cu is at a minimum because Cu(II) is not adsorbed on γ-Al2O3 and natural organic matter is adsorbed. Inert CuL complexes were adsorbed at pH 8.0 on γ-Al2O3, ‘Aerosil 200’, CaCO3, and chrysotile but they were not adsorbed on northupite. The voltammetric method can be recommended for use in natural waters for distinguishing between metal ionic and metal inert complex species which are adsorbed from solution onto various solid particles.
