Study on the chemical oscillation in tyrosine-KBrO3-H2SO4 system

Abstract

The chem. oscillating system of tyrosine-KBrO3-H2SO4 is described. This system not only includes oscillation, in the presence of Ce3+, Mn2+, and Fe(Phen)2+3 as catalysts, but also induces uncatalyzed oscillations in the absence of metal ions. The effects of many factors on the oscillations were investigated. A mechanism for the uncatalyzed oscillation of this system is proposed.
