Ligand exchange with dimethylglyoxime (DMG) and dif ferential pulse cathodic stripping voltammetry (DPCSV) was applied to determine free Co(II) ionic concentrations [Co2+] and Co(II) complexation by natural organic ligands in freshwater. [Co2+] and the complexing parameters were calculated on the ba...
