Abstract
Abstract. The Clarke-Nikolsky oxidation potential
method was used to study complex formation in the Fe(II)–Fe(III)–Gly–Na(H)ClO4–H2O
system at a temperature of 308.15 K, I = 0.50, CFe(II)
= CFe(III) = 1.10–3, and CGly
= 2.10–3 mol/L in the pH range of 0.5–8.5. Experimental
curves of the system EMF dependence on concentration parameters: pH, pCFe(III),
pCFe(II), pCL. For the calculation of complex formation
constants, the method of successive approximation of the theoretical and
experimental oxidation functions using the Excel
program was used.
Key words: iron(II),
iron(III), glycine, coordinating connections, dependence, E.M.F., stability,
