Sažetak
Characteristics of iron(III) complexes with malic acid in 0.55 mol L^-1 NaCl were investigated by voltammetric techniques. Three iron(III)-malate redox processes were detected in the pH range from 4.5 to 11: first one at -0.11 V, second at -0.35 V and third at -0.60 V. First process was reversible, so stability constants of iron(III) and iron(II) complexes were calculated: log K1(FeIII(mal))= 12.66±0.33, log β2(FeIII(mal)2)= 15.21±0.25, log K1(FeII(mal))= 2.25±0.36, and log β2(FeII(mal)2)= 3.18±0.32. In the case of second and third reduction process, conditional cumulative stability constants of the involved complexes were determined using the competition method: log β(Fe(mal)2(OH)x)= 15.28±0.10 and log β(Fe(mal)2(OH)y)= 27.20 ± 0.09.
