An Overview and Evaluation of Highly Porous Adsorbent Materials for Polycyclic Aromatic Hydrocarbons and Phenols Removal from Wastewater
This review evaluated highly porous adsorbent materials — including activated carbons, metal-organic frameworks, and zeolites — for removing polycyclic aromatic hydrocarbons (PAHs) and phenolic compounds from wastewater. These priority pollutants co-occur with microplastics in contaminated water bodies, and porous adsorbents show high removal efficiency across multiple compound classes.
