Radical-controlled Oscillations in BrO3^--fructose-Mn^2＋-H2SO4 System

Sustained oscillations were observed in the BrO3^--fructose-Mn^2+-H2SO4 system. Unlike the classical BZ oscillations, the present oscillations might be considered as radicalcontrolled rather than bromide-controlled since no substance subjected to bromination was present. Addition of acetone induced dual-frequency oscillations comprised of both the radical-controlled and the bromide-controlled oscillations. (共4页)
