Over the past decade, biochar application in water treatment has gained prominence, particularly in the realm of wastewater treatment. A recent bibliometric analysis, encompassing 2673 publications from 2011 to 2022, sheds light on the global landscape of biochar adsorption research. China emerges as the frontrunner in this field, leading the pack in published articles. The focal point of this research lies in the magnetic adsorption of biochar in wastewater.

Despite the comprehensive range of wastewater types that biochar can effectively treat, the review underscores the variability in adsorption mechanisms concerning heavy metals, inorganic salts, and organic pollutants. The analysis delves into factors influencing biochar’s performance in pollutant adsorptionBiochar has a remarkable ability to attract and hold onto pollutants, like heavy metals and organic chemicals. This makes it a valuable tool for cleaning up contaminated soil and water. More and suggests measures to enhance its functional characteristics. The future trajectory of biochar research is proposed to center around augmenting the adsorption capacity of biochar products.

This synthesis of information not only provides insights into the historical and current trends in biochar research but also lays the groundwork for future exploration. With practical applications in mind, this research aims to address water pollution challenges and contribute to the overall enhancement of environmental quality.
