EQUILIBRIUM STUDIES ON BIVALENT TRANSITION METAL CHELATES WITH BIOLOGICALLY ACTIVE SCHIFF?S BASE OF HETEROCYCLIC ALDEHYDES

摘要

It has been observed that Schiff’s bases derived from substituted furan or furyl glyoxal possess antifungal activity. The fungal toxicity increases with chelation of these compounds with metals. Metal ligand stability constant of above systems are to be determined by Calvin Bjerrum pH metric titration technique as adopted by Irving-Rossotti
