Abstract:

In the present study, we have explored the binding abilities of powerful dipodal chelator ligand N1,N3-bis(2-(((Z)-2,3-dihydroxybenzylidene)amino)ethyl)malonamide (MEC) to trivalent metal ions. We have investigated the coordination behavior of the dipodal ligand MEC with the trivalent metal ions Al3+, Fe3+, and Cr3+ in aqueous media ranging from pH 2 to 11, employing potentiometry and spectrophotometry techniques. Results shows the higher binding ability of Cr+3 metal ion among all metal ions with largest formation constant value, log β = 28.56.
