Biochar, derived from the carbonization of organic waste, is gaining recognition for its potential in environmental remediation, particularly for antibiotic-laden wastewater. A recent study published in the Journal of Environmental Management delves into the scientometric landscape of biochar’s application in this field, using tools like CiteSpace and VOSviewer to analyze 1,162 papers from 2011 to 2023.

The research highlights three key phases in the development of biochar for antibiotic remediation: applied methods, mechanism investigation, and enhanced improvement. It identifies that biochar’s ability to remediate antibiotics is primarily due to interactions such as π-π electron donor-acceptor, hydrophobic, electrostatic, hydrogen-bonding, and pore filling. Enhancements through steam activation, acid/base treatment, and metal modifications improve biochar’s properties, making it more effective.

One of the most promising areas of current research is biochar activated persulfate, which utilizes both free radical and non-free radical pathways to degrade antibiotics. Despite these advancements, further research is necessary to optimize biochar’s capabilities and address the challenges of its practical application.

The study underscores the importance of biochar in treating antibiotic pollutants, emphasizing its environmental benefits and efficiency. As antibiotic pollution continues to rise, biochar’s role as an effective and sustainable solution offers significant promise for future water treatment technologies.
