This review primarily focuses on the advancement of biochar research methods and their application in treating soil pollution agriculture. Biochar, a novel material for treatment, shows great potential because its high specific surface area, abundant functional groups, well-developed pore structure. work first introduces current state hazards limitations traditional remediation technologies. It then discusses advancements preparation techniques. paper also discussed agricultural field. Although has shown many advantages remediation, technical economic issues production remain to be resolved, long-term environmental impacts ecological safety need further evaluated. Future should focus modification optimization fully realize sustainable development.

The effect and mechanism of phenol removal by immobilized microorganisms in Fe3O4 nanomaterial-modified pharmaceutical residue biochar was investigated to develop efficient immobilizing microbial technology. Plant (Y3, Y5, Y7) prepared from Andrographis paniculata plant residues as the raw material at 300 °C, 500 700 respectively. Y7 modified with nanomaterial (Fe-Y7). These four kinds biochars were used carriers adsorb Alcaligenes faecalis strain JH1, JY3, JY5, JY7, Fe-Y7 investigate removal, eight cycles performed analyze their immobilization performance. Compared suspended bacteria, biochar-immobilized bacteria could improve tolerance different environments. At temperatures 25 °C 40 pH = 5~9, initial concentration 300–500 mg/L, salinity 3%, still grow maintain strong activity within 48 h. water-extractable organic carbon also tested for degradation which found have stimulating effects on bacteria. In batch experiments, number increased, grew adhered rapidly biochar, eventually forming a thick sticky biofilm. After sixth cycle, all remove mg/L solution 12 rate JFe-Y7 relatively fast eighth cycle. results indicated that good durability, stability, reproducibility nanoparticle modification increasing adsorption amount, capacity enzymatic
