Study of interaction between vitamin C and nickel (II)‎ ion using a Polarographic methods

Abstract EN

The Polarographic study of the interaction between ascorbic acid and Ni+2 was carried out at dropping mercury electrode [DME].

This study included the determination of the kinetic parameters (kfh,n) and thermodynamic parameters such as enthalpy change (H), free energy change (G) and entropy change (S) of Ni+2 complexes with ascorbic acid in 0.1 M KCl solution over the temperature rang of (294-309) K.

The electrode processes were irreversible and diffusion controlled.
