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.
