Binary Complexes of Aspartic Acid with Some Metal Ions in Aqueous Solution and Water-dioxane Mixtures

Ebrahim Ghiamati, Maliheh Baniasadi & Alireza Farrokhi · Chemical Science International Journal · 2017

The reaction between amino acids and metal ions has been used as a model for transferring the metallic ions to body tissues. How stable these complexes are formed is our concern. The stability constants of the complexes between L-aspartic acid (Asp) and Co(II), Ni(II), Cu(II), Zn...

Determination of the Formation Constant of Some Transition Metal Ion- histidine Complexes in Water and Water-dioxane and Evaluation of their Thermodynamic Parameters

Ebrahim Ghiamati & Ehsaneh Jalaeian · Asian Journal of Physical and Chemical Sciences · 2017

Aims: The formation constants of histidine complexes of Fe (III), Co (II), Ni (II), Cu(II), Zn (II) and  Pb (II) at temperatures of  25, 30, 37, 45°C were determined potentiometrically, utilizing modified Bjerrum's method. Potentiometric titrations were carried out in 30% and 70%...
