Formation of Metal Complexes with Ethylenediamine: a Critical Survey of Equilibrium

At present ethylenediamine is one of the more studied nitrogen— —ligands. The main physico—chemical properties of this diamine are reported in this survey. The fundamental techniques for its purification and storage and its acid—base characteristics in aqueous solution are described. The formation constants of the complexes with various metal ion, the thermodyna mic values relative to the react...

Polarographic and Spectrophotometric Study of Lead Complexes w

Foram estudados aspectos experimentais e teóricos sobre o comportamento do complexo de chumbo com dietanolditiocarbamato (DEDC), em solução. A reação ocorre através da formação de um precipitado amarelo, o qual é solúvel em excesso de ligante e alguns solventes polares. Os resultados das análises, elementar e gravimétrica, mostram uma relação estequiométrica de 1:2 (Pb:DEDC), comprovada nos est...

Spectrophotometric Study of New Schiff Base Complexes with Some Metal Ions in Methanol Solution

The complexation reactions between N,N'-3,6-dioxa-1,8-octanebis (salicylaldimine) [saldioxen(I)] and Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II) were studied spectrophotometrically in methanol solution at 25 °C. The stoichiometry of the complexes were obtained as 2:1 and 1:1 sadioxen-metal ion using mole ratio method. The formation constants of the complexes were determined, a...

Differential Pulse Anodic Stripping Voltammetric Study of Zinc- Ethylenediamine Complex

Differential pulse anodic stripping voltammetric study of zinc-ethylenediamine complex has been investigated using thin mercury film coated glassy carbon electrode at 30°C. The overall work was carried out at constant ionic strength (I = 0.20 mol dm -3 ) and pH (9.10±0.10). The electrode processes were found to be reversible and diffusion controlled. The results revealed that zinc forms three (...
