Abstract

Kinetics of oxidation of formaldehyde, formic acid and formate anion by peroxomonosulfate (PMS) were studied. Formaldehyde is oxidized both by HSO −5 and SO 2−5 , whereas formic acid and formate ion are oxidized by SO 2−5 alone. The kinetic results show that the formaldehyde is ∼103 times more reactive than formic acid, which in turn reacts ∼102 times faster than formate anion. Mechanisms are discussed in terms of the kinetic results.

Abstract

Изучена кинетика окисления формальдегида, щавелевой кислоты и форматных анионов пероксомоносульфатом. Формальдегид окисляется как с помоью HSO −5 , так и с помощью SO 2−5 , а щавелевая кислота и форматный ион окисляются только с помощью SO 2−5 . Из кинетических данных следует, что формальдегид прибл. в 103 раз более реакционноспособен, чем щавелевая кислота, которая, в свою очередь, прибл. в 102 раз реагирует быстрее, чем форматный анион. На основе кинетических данных обсуждается механизм реакции.
