摘要

•Magnetic biochar prepared from biomass waste by microwave pyrolysis/precipitation.•Non-stoichiometric nano-maghemite enhances surface texture.•Magnetic biochar as an effective adsorbent of arsenic and methylene blue.•Short microwave irradiation increases the arsenic desorption rate.•Degradation of methylene blue by microwave regeneration controlled by HPLC/ESI-MS.
