Abstract: A pH-potentiometric titration method has been used to determine the acid dissociation constants of octasulfonato-octakis(carboxy) calix[8]arene and cumulative stability constants complexes of octasulfonato-octakis(carboxy) calix[8]arene with transition element at 30℃, and ionic strength I=0.1. It has been found that ligand can from such coordination compounds as MHnL(n=1-7) with transition element. Which has not been reported up to now. |
