Abstract

A non-enzymic system containing CuSO4 (10 mmol/L) and hydrogen peroxide (100 mmol/L) was used for the degradation of three polycyclic aromatic hydrocarbons: phenanthrene, fluoranthene, and pyrene (all at 10 mmol/L). The system degraded the compounds rapidly and efficiently. After 1 d at room temperature, more than 80% of pyrene, phenanthrene, and fluoranthene disappeared. Several products are formed during the reaction including a black precipitate.

摘要

一个含有硫酸铜(10毫摩尔/升)和过氧化氢(100毫摩尔/升)的非酶体系被用于降解三种多环芳烃:菲、荧蒽和芘(浓度均为10毫摩尔/升)。该体系能快速且高效地降解这些化合物。在室温下放置1天后,芘、菲和荧蒽的含量消失了80%以上。反应过程中形成了几种产物,包括一种黑色沉淀。
