Abstract

The BrO(3)(-)-SO(3)(2-)-Fe(CN)(6)(4-) (BSF) pH-oscillatory system is coupled to the Al(OH)(3) precipitation equilibrium (BSFA system) and studied in a stirred flow reactor. The dynamic behavior of the BSFA system differs significantly from that of the BSF system. In addition to the large-amplitude pH oscillations found in the BSF system, new small-amplitude and mixed-mode oscillations occur. A detailed mechanism of the BSFA system is developed and investigated.

摘要

溴酸根离子-亚硫酸根离子-亚铁氰根离子（BSF）pH振荡体系与氢氧化铝沉淀平衡相耦合（BSFA体系），并在搅拌流反应器中进行研究。BSFA体系的动力学行为与BSF体系有显著差异。除了在BSF体系中发现的大幅pH振荡外，还出现了新的小幅振荡和混合模式振荡。本文建立并研究了BSFA体系的详细机理。
