Reed biochar by microwave-assisted pyrolysis for the removal of tetracycline in water.

This study uses reed straw and phosphoric acid to synthesize reed biochar and modified reed biochar through tubular furnace pyrolysis and microwave-assisted pyrolysis, respectively. The effects of pyrolysis temperature and phosphorous acid on the structure, composition, porosity, and adsorption performance of tetracycline (TC) were further investigated. The results showed that the modified biochar prepared by microwave-assisted pyrolysis had better performance.
