摘要

用经典的Clark-Nikolsky氧化电位方法研究了298.15 K下Fe(II) -Fe (III) -L-Ala-H2O体系中配位化合物的形成过程和1.0 mol/L Na(H)ClO4背景下溶液的离子强度。通过对所得到的体系电动势随基本粒子浓度参数变化的实验曲线的联合分析，可以确定下列配合物的形成：[FeHL(H2O)5]3+, [Fe(HL)2(H2O)4]3+, [Fe2(HL)2(OH)4(H2O)6]2+, [Fe(III)Fe(II)(HL)2(OH)4(H2O)6]+, [FeHL(H2O)5]2+, [Fe(HL)(OH) 4]+，和[Fe(HL)(OH)2(H2O)3]0。

A Study of the Processes of Complex Formation in a Fe(II)–Fe(III)–L-Ala–H2O System

The processes of the formation of coordination compounds in a Fe(II)–Fe(III)–L-Ala–H₂O system at 298.15 K and the ionic strength of a solution of 1.0 mol/L against the background of Na(H)ClO₄ are studied by the classical method of the Clark–Nikolsky oxidation potential. A joint analysis of the obtained experimental curves of the dependence of the electromotive force of the system on the concentration parameters of basic particles makes it possible to determine the formation of complexes with the following compositions: [FeHL(H₂O)₅]³⁺, [Fe(HL)₂(H₂O)₄]³⁺, [Fe₂(HL)₂(OH)₄(H₂O)₆]²⁺, [Fe(III)Fe(II)(HL)₂(OH)₄(H₂O)₆]⁺, [FeHL(H₂O)₅]²⁺, [Fe(HL)(OH)(H₂O)₄]⁺, and [Fe(HL)(OH)₂(H₂O)₃]⁰.
