Abstract
AbstractWater pollution caused by organic micro‐pollutants is seriously harmful to aquatic ecosystem and human health. In this work, a hierarchical porous aerogel (HPAG) prepared from rigid conjugated polymers is used to remove organic micro‐pollutants from water. Thanks to the hierarchical porous structure and rich π electrons, HPAG showed a fast adsorption rate and high adsorption capacity for adsorbates. The maximum equilibrium adsorption capacity of HPAG for bisphenol A, 1‐naphthylamine, and naphthalene is 60.5, 50.9 and 63.9 mg g−1 at 10 ppm, respectively, and the adsorption behaviors were in accordance with the Freundlich model. HPAG exhibited a high preference in adsorbing organic micro‐pollutants with high hydrophobicity, and the removal efficiency for polycyclic aromatic hydrocarbons reached over 95%. The HPAG can be easily recycled and regenerated after washing with dichloromethane, and the adsorption performance maintained above 82% after 5 cycles.
