Highly Efficient Adsorption of Norfloxacin by Low-Cost Biochar: Performance, Mechanisms, and Machine Learning-Assisted Understanding.

ABSTRACT: This study employed potassium carbonate (K₂CO₃) activation using ball milling in conjunction with pyrolysis to produce biochar from one traditional Chinese herbal medicine Atropa belladonna L. (ABL) residue. The resulting biochar KBC₈₀₀ was found to possess a high specific surface area (S _BET = 1638 m²/g) and pore volume (1.07 cm³/g), making it effective for removing norfloxacin (NOR) from wastewater. Batch adsorption tests confirmed its effectiveness in eliminating NOR, along with its excellent resistance to interference from impurity ions or antibiotics. Notably, the maximum experimental NOR adsorption capacity on KBC₈₀₀ was 666.2 mg/g at 328 K, surpassing those of other biochar materials reported.
