摘要

摘要: 多環芳烴（PAHs）是近年來在大氣污染問題中逐漸受到關注的一類污染物，不僅其自身嚴重威脅著人體健康，還可作為低揮發性物質促進二次顆粒物的生長.世界多國開始不斷通過各種技術手段對廢氣中PAHs的排放進行控制，PHAs已成為大氣環境領域共同關注的熱點問題.吸附法是最具潛力且已被工業應用認可的一類PAHs控制凈化關鍵技術，吸附劑對PAHs的吸、脫附性能是其中的關鍵.目前國內外學者無論是基于傳統碳類吸附劑，還是新型的介孔吸附劑，都針對此類特殊低揮發性氣體的吸附相平衡、動力學以及脫附特性做了相關研究，探悉了獲取PAHs吸脫附最優平衡的關鍵因素以及最適吸附劑.本文針對這些結果及相關應用進行了綜述，對比分析了介孔吸附劑較傳統吸附劑在PAHs吸脫附特性上呈現的優勢，旨在為PAHs及其他低揮發性氣體吸附凈化的相關工作提供有效參考.

Abstract: Polycyclic aromatic hydrocarbons (PAHs) are pollutants that have attracted great attention in recent years regarding the issue of atmospheric pollution. Being harmful to human health, PAHs also promote the growth of secondary particles. Consequently, several countries have begun to control the emission of PAHs in exhaust gases with different techniques, which is a hot topic in the atmospheric environment field. Adsorption is one of the most significant methods and has been accepted by industries, of which the adsorbent properties are key factors. Researchers have studied the adsorption equilibrium, kinetics, and desorption properties of PAHs as special low-volatile gases on conventional activated carbons and novel mesoporous adsorbents. They have also examined the optimal balance between adsorption and desorption based on the corresponding adsorbents. In this paper, these results and related applications are reviewed, and the advantages of mesoporous adsorbents over traditional adsorbents on purifying PAHs are specifically analyzed. This work can be a reference for future studies on the adsorption purification of PAHs and other low-volatile gases.
