多环芳烃光降解研究进展

Advances in study on photolysis of polycyclic aromatic hydrocarbons

概述了多环芳烃(PolycyclicAromaticHydrocarbons,PAHs)在液相、固相和气相介质中的光降解过程及应用定量结构-性质关系(QuantitativeStructure-PropertyRelationships,QSPR)模型预测PAHs光降解的研究进展。在此基础上,对今后一段时期PAHs光降解研究提出几点看法。

The present article introduces the up-to-date advances in the study of the photolysis of polycyclic aromatic hydrocarbons (PAHs). First of all, the authors have made a detailed review of the photodecomposition of PAHs in liquid medium, on solid matrix and in gaseous medium and the applications of QSAR model so as to make a clear prediction of the processes of photolysis of PAHs. And, then, on the basis of the above summary, the author has come up with some proposals on the research of photolysis of PAHs in the near future. Needless to say, much more work remains to be done, such as the mechanism of photolysis of PAHs as well as seeking of new semiconductor catalyzers so as to find out ways to their practical application to PAHs photolysis.
