摘要：
If sulfonato ligands are to be used in metal ion preconcentration techniques based on ion-exchange, the chelate stability constant must be available. An ion-exchange procedure is described for the determination of the stability constants for some metal-Plasmocorinth B complexes. The results are compared with those obtained spectrophotometrically. log K values are in good agreement for two methods. The enrichment of anionic complexes is obtained with an ion-exchange procedure.
