Abstract: The equilibrium constants and oxygenation constants of ethylenediamine Co complex (en Co(Ⅱ)) were determined by potentiometry method. The oxygenation species and their formation conditions have been investigated as well. Two oxygenation species: (Coen3)2O2 and (Coen2)O2(Coen3) found in potentiometry were verified by spectrophotometry and oxygen electrode titration.

Key words: oxygen carrier, ethylenediamine, cobalt complex, oxygenation
