Abstract

A complex “two-spike” shape of CL oscillations is shown to be caused primarily by the sharp increase in the concentration of hydroxymalonyl radicals due to the drop in those of HOBr and BrO .2 , reacting rapidly with these radicals and hydroxymalonic acid itself at the critical concentration of Br− in the system.

Abstract

Показано, что сложная “двухпичковая” форма колебаний І обусловливается, в первую очередь, резким возрастанием концентрации гидроксималонильных радикалов вследствие падения концентрации HOBr и BrO .2 , быстро реагирующих с этими радикалами и самой гидроксималоновой ислотой, при достижении в системе критической концентрации бромид ионов.
