摘要：

Complexation of iron(II) in aqueous glycine (alpha-aminoacetic acid) solutions is studied in the pH range 1.0-8.0 at 298.16 K at various ionic strengths (NaClO4). The stability constants of the resulting complexes go down as the ionic strength of the solution increases. The stability constants of the complexes are determined using the experimental "electromotive force of the system versus pH" curves by iterative fitting of the theoretical oxidation function to the experimental one with the Excel program. The correlation between the stability constants of complexes and ionic strength of the solution is also calculated using the Debye-Huckel equation and SigmaPlot 10.0 software. Statistical analysis of the calculated data is performed with P value of 0.95.
