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.

Fe(III) 离子诱导氧化钒 (IV) 与 2,2'-联吡啶的亚氨基二乙酸盐络合物的水合反应:动力学研究

[VO(ida)(bipy)]·2H2O (VO(ida)(bipy)) 复合物(其中ida = 亚氨基二乙酸根阴离子和bipy = 2,2'-联吡啶)的水合反应动力学由[Fe( H2O)6]3+ 离子在水溶液中进行了研究。分光光度研究在 293.15–313.15 K 范围内的不同温度下进行。 [Fe(H2O)6]3+ (Fe3+) 离子的浓度保持在 2 × 10–4 至 8 × 10– 范围内4 mol L-1,VO(ida)(bipy)的浓度为1×10-3 mol L-1。基于 Glint 计算机程序计算可观察到的反应速率常数的值。此外,还提出了由 Fe(III) 离子诱导的 VO(ida)(bipy) 水合的机制。
