Abstract
Nonenzymatic decomposition of hydrogen peroxide proceeded more rapidly in ice than in liquid water. At 5 x 10-7M ferric chloride or 10-8M cupric chloride, breakdown of hiydrogen peroxide was significant at -11° and -18° but negligible at +1°C. Ascorbic acid oxidation was faster in ice both with or without added metalion. Nonparallel effects of metals and pH indicate, mechanism changes in ice.This publication has 10 references indexed in Scilit:
