Abstract

The kinetics of the aquation reaction of the [VO(ida)(bipy)]·2H2O (VO(ida)(bipy)) complex (where ida = iminodiacetate anion and bipy = 2,2’-bipyridine) promoted by [Fe(H2O)6]3+ ions were investigated in aqueous solutions. Spectrophotometric studies were carried out at different temperatures in the range of 293.15–313.15 K. The concentration of the [Fe(H2O)6]3+ (Fe3+) ions was kept within the range of 2 × 10–4 to 8 × 10–4 mol L–1, and the concentration of VO(ida)(bipy) was 1 × 10–3 mol L–1. The values of the observable reaction rate constants were calculated based on the Glint computer program. Furthermore, the mechanism for the aquation of VO(ida)(bipy), induced by Fe(III) ions, has been proposed.

铁离子诱导氧化钒(IV)与2,2′-联吡啶的亚氨基二乙酸配合物的水化反应动力学研究

研究了[Fe(H2O)6]3+离子在水溶液中促进[VO(ida)(bipy)]·2H2O (VO(ida)(bipy))配合物(ida =亚氨基二乙酸阴离子，bipy = 2,2′-联吡啶)的水化反应动力学。在293.15 ~ 313.15 K的不同温度下进行了分光光度研究。[Fe(H2O)6]3+ (Fe3+)离子浓度保持在2 × 10-4 ~ 8 × 10-4 mol L-1范围内，VO(ida)(bipy)浓度为1 × 10-3 mol L-1。利用Glint计算机程序计算了可观测到的反应速率常数。此外，还提出了由Fe(III)离子诱导VO(ida)(bipy)水化的机理。
