pH-metric studies on some ternary complexes of lanthanones
Tóm tắt
Stepwise mixed ligand complex formation has been cited for the formation of 1∶1∶1,Ln(III)—NTA—catechol ternary complexes potentiometrically [whereLn(III)=La(III), Pr(III) or Nd(III)]. The results of titration curves indicate the formation of 1∶1,Ln(III)—NTA complexes in beginning and the addition of catechol, takes place later on in the higher buffer region. The relative stability of these ternary complexes in terms of metal ion has been reported as La(III)<
