吸附法去除环境中多环芳烃的研究进展
Advances on the removal of polycyclic aromatic hydrocarbons in environment by adsorption
摘要
Abstract
Adsorption has become a prevailing technique to remove polycyclic aromatic hydrocarbons (PAHs) in environment due to its low cost,easy operation and easy recovery. This paper reviewed the latest development of adsorption mechanism and the commonly used adsorbents for PAHs. The adsorption mechanisms includingπ-π interaction,acid-base theory,π-complexation and hydrophobic interaction have been well illustrated. Then we summarized the research progress on adsorbents,such as bio-materials,soil,carbon materials and mesoporous materials,etc. The influence of the material modification on the adsorption capacity was discussed from the perspective of adsorption mechanism. Furthermore,we analyzed the pros and cons and the applications of these adsorbents,which may provide a direction for the exploration of efficient adsorbents for the removal of PAHs. However,the main challenge is that the adsorbents are difficult to recycle and reuse and easy to produce secondary pollution,which is also the major obstacle for the large-scale industrial applications. Therefore,the development,modification,and recycling usage of novel and high-efficiency adsorbents,and the understanding of the underlying adsorption and regeneration mechanisms will be the main research directions for PHAs removal.关键词
