摘要
水环境中的铜主要以配合物形式存在,大多具有光化学活性。由于铜在光化学过程中的氧化还原循环可以导致其配体以及水体中有机污染物的降解,所以铜及其配合物在污染修复技术中的应用逐渐受到关注。本文综述了水环境中铜的光化学研究进展以及在多相和均相光催化体系中铜对污染修复的影响。
Most of the cupric ions in aquatic systems are complexed with various ligands. These complexes are liable to photochemical reactions. Photodegradation of the organic ligands as well as other organic pollutants is often involved in the redox cycles of copper under solar irradiation. Photochemical mechanisms of the copper complexes in aquatic systems are reviewed. The role of copper in heterogeneous and homogeneous photocatalytic systems and hence the implications of these processes in environmental remediation are also discussed.
