Magnetically responsive low-cost adsorbents for aniline removal
Aniline (benzenamine) is a very important substance used in industry even though it is classified as very toxic. The need for a practical solution to remove it from the environment is still a current topic. Aniline adsorption from water solution was evaluated using low-cost, magnetically responsive...

| description | Aniline (benzenamine) is a very important substance used in industry even though it is classified as very toxic. The need for a practical solution to remove it from the environment is still a current topic. Aniline adsorption from water solution was evaluated using low-cost, magnetically responsive adsorbents of different type (plant derived materials, microbial and algae biomass, carbon-based and inorganic materials). Magnetic modification, based on the deposition of magnetic iron oxide particles on material surface, enabled rapid adsorbent separation from the analyzed solutions. Carbon-based materials including activated charcoal and biochars exhibited the best adsorption properties. Biochar pyrolysis temperature substantially influenced its affinity for aniline adsorption. Maximum adsorption capacity for magnetically modified spruce biochar pyrolyzed at 1200 °C was 75.7 mg/g. |
