摘要
报道了氟离子对Ce(SO4) 2 KBrO3 CH2 (COOH) 2 H2 SO4(B Z)振荡体系的干扰 ,考察了在 5× 10 - 5～ 1× 10 - 3 mol L范围内 ,F- 的浓度与振荡反应周期的改变ΔTP 之间的关系。结合FKN机理模型 ,提出了F- 干扰振荡反应的机理 。
It is first reported that the effect of fluoride on Belousov-Zhabotinsky oscillating reaction. The results show that the oscillating period increase is linearly proportional to the fluoride concentration over the range of 5.0 x 10(-5) similar to 1.0 x 10(-3) mol/L. The reaction mechanism is proposed according to the interaction between fluoride and the catalyst metal ion as well as Field-Koros-Noyes (FKN) mechanism.
