“…Furthermore, at pH 6.0−7.0, the surface of Fe/Zn-biochar was negatively charged, while tetracycline was in a neutral form, resulting in the lowest electrostatic repulsion and the highest adsorption capacity. 133 Meghani et al 134 demonstrated that the zinc-activated ginger-waste biochar showed high adsorption capacities, effectively removing oxacillin, ciprofloxacin, enrofloxacin, chlortetracycline, and doxycycline from the aqueous, with a removal efficiency of more than 95%. This is attributed to ZnCl 2 , a Lewis acid, serving as a dehydration agent during pyrolysis, promoting an increased surface area and biomass porosity of biochar.…”

The increasing use of antibiotics induces the spread of antibiotic-resistant genes (ARGs) in the environment, which seriously threatens the natural ecosystem and human health. Reducing antibiotics in the environment is of the utmost importance. Biochar, as a cost-effective, environmentally friendly, and carbon-rich porous material with circular economy prospects, has shown great potential in antibiotic remediation in the environment. The adsorption mechanisms (e.g., electrostatic interaction, hydrogen bonding interaction, hydrophobic interaction, π−π electron donor−acceptor (EDA) interaction, and pore diffusion) and the biotic roles (e.g., biochar as a microbial shelter, carrier, and electron mediator) synergistically promote antibiotic removal from the aqueous phase. This review critically discusses various removal mechanisms based on classes of antibiotics, the efficacy of biochar in antibiotics removal, and the influence of crucial parameters on the removal of antibiotics. Furthermore, the review provides a critical discussion on engineering the application of biochar. Finally, the review highlights the prospects and challenges of biochar application in treating antibiotic-contaminated liquid streams.
