Abstract
The solvent extraction method for characterization of strong complexing agents in natural waters has been developed. The titration curve the relationship between the concentration of a metal added in a sample solution and that of the metal in the organic phase after extraction, has been modelled on the basis of Ringbom's theory. The concentration of the metal in the organic phase is easily calibrated by the activities of the radioisotopic spike. The conditional stability products for complexation of natural ligands with cobalt (57Co), manganese (54Mn) and zinc (65Zn) were calculated from the titration curves.
