摘要

摘要利用紫外光谱法、高效液相色谱法和化学分析法研究了丙二醛（MDA）在酸性（pH 3）和碱性（pH 11）水溶液中的辐射分解。研究发现，在酸性介质中，当 MDA 的浓度大于 3 × 10-4 mol/L 时，其降解的辐射-化学产率超过 10 个分子/100 eV，这表明存在链式过程。研究证实，溶解氧在 MDA 分解的链式过程中起着重要作用。提出了一个反应系统来解释实验结果。

Radiation-Chemical Decomposition of Malondialdehyde in Aqueous Solutions

Abstract

The radiolysis of malondialdehyde (MDA) in acidic (pH 3) and alkaline (pH 11) aqueous solutions has been studied using UV spectrometry, HPLC, and chemical analysis. It has been found that in an acidic medium, the radiation-chemical yield of degradation of MDA at concentrations greater than 3 × 10^–4 mol/L exceeds 10 molecule/100 eV, indicating the occurrence of chain processes. It has been established that dissolved oxygen plays an important role in the chain process of MDA decomposition. A system of reactions was proposed to explain the results of the experiments.

期刊介绍： High Energy Chemistry publishes original articles, reviews, and short communications on molecular and supramolecular photochemistry, photobiology, radiation chemistry, plasma chemistry, chemistry of nanosized systems, chemistry of new atoms, processes and materials for optical information systems and other areas of high energy chemistry. It publishes theoretical and experimental studies in all areas of high energy chemistry, such as the interaction of high-energy particles with matter, the nature and reactivity of short-lived species induced by the action of particle and electromagnetic radiation or hot atoms on substances in their gaseous and condensed states, and chemical processes initiated in organic and inorganic systems by high-energy radiation.
