Adsorption of Tetracycline by Ammonium Molybdate Modified Chinese Fir Biochars

Tetracycline (TC) adsorption amount on original wood biochar was finitely, so modification is imperative to improve its capacity. This study mixed chinese fir sawdust with ammonium molybdate prepare a modified (MCB) via pyrolysis at 800 °C. Meanwhile, pristine (CB) produced as control. The effects of pH, time, initial concentration and adsorbent dosage the process were also studied. Langmuir model quasi second-order kinetic used describe characteristics process. optimally capacity TC MCB reached 36 mg/g, which 6 – fold increase CB. Therefore, by can be potential way for increasing from antibiotic sewage water.
