Volatile organic compounds (VOCs) are a crucial kind of pollutants in the environment due to their obvious features of severe toxicity, high volatility, and poor degradability. It is particularly urgent to control the emission of VOCs due to the persistent increase of concentration and the stringent regulations. In China, clear directions and requirements for reduction of VOCs have been given in the "national plan on environmental improvement for the 13th Five-Year Plan period". Therefore, the development of efficient technologies for removal and recovery of VOCs is of great significance. Recovery technologies are favored by researchers due to their advantages in both recycling VOCs and reducing carbon emissions. Among them, adsorption and membrane separation processes have been extensively studied due to their remarkable industrial prospects. This overview was to provide an up-to-date progress of adsorption and membrane separation for removal and recovery of VOCs. Firstly, adsorption and membrane separation were found to be the research hotspots through bibliometric analysis. Then, a comprehensive understanding of their mechanisms, factors, and current application statuses was discussed. Finally, the challenges and perspectives in this emerging field were briefly highlighted.
挥发性有机化合物（VOCs）是环境中一种至关重要的污染物，因为它们具有明显的毒性大、挥发性高、难降解等特点。由于浓度持续增加和严格的法规，控制 VOCs 的排放显得尤为紧迫。在中国，“十三五”环境改善国家计划”给出了减少 VOCs 的明确方向和要求。因此，开发高效的 VOCs 去除和回收技术具有重要意义。回收技术受到研究人员的青睐，因为它们在回收 VOCs 和减少碳排放方面都具有优势。其中，吸附和膜分离工艺由于具有显著的工业前景而得到了广泛研究。本文综述了吸附和膜分离在去除和回收 VOCs 方面的最新进展。首先，通过文献计量分析发现吸附和膜分离是研究热点。然后，讨论了它们的机理、影响因素和当前应用现状。最后，简要强调了这个新兴领域的挑战和展望。
