Ethanol combined-ball milling was used to modify corn-stover biochar. The adsorption performance and mechanisms of aqueous norfloxacin (NOR) onto the resulting biochar (C2H6O-BC) were evaluated. Ball-milling modulated its surface oxygen-containing functional groups enhanced specific area. capacity C2H6O-BC 163 mg·g−1, about 72% equilibrium could be reached within 60 min. electrostatic interaction not dominant mechanism when initial pH lower than 8.00. antagonistic effect Cu(II) on NOR observed. fixed-bed column showed potential remove spontaneously. Sequential two-stage batch reaction experiment that it a fast efficient technology using C2H6O-BC. suggested as π-π interactions, H-bonding pore-filling. In summary, ethanol-combined ball in this study provided an adsorbent for NOR.

With the growth of global population and acceleration industrialization, problem water pollution has become increasingly serious, posing a major threat to ecosystem human health. Traditional treatment technologies make it difficult cope with complex pollution, so scientific community is actively exploring new efficient methods. Biochar (BC), as low-cost, green carbon-based material, exhibits good adsorption catalytic properties in due its porous structure abundant active functional groups. However, BC's pure or capacity limited, researchers have dramatically enhanced performance through modification means, such loading metals heteroatoms. In this paper, we systematically review recent applications BC modified materials for adsorption, Fenton-like, electrocatalytic, photocatalytic, sonocatalytic systems, discuss their adsorption/catalytic mechanisms. most research field at laboratory simulation stage still needs much improvement before can be applied large-scale wastewater treatment. This improves understanding pollutant mechanisms BC-based materials, analyzes limitations current studies, investigates future directions.

Developing algae cultivation for food, chemicals, and bio-energy generates a significant amount of algal waste/residue after utilization. Meanwhile, harmful blooms caused by abnormal proliferation various produce large biomass, posing serious harm to human health, the environment economy. Converting body biochar is crucial method with which take advantage this resource. Biochar usually has specific surface area, developed pore structure, high cation exchange capacity rich functional groups. With stable physical/chemical properties easy modification techniques, posited as an ideal adsorption material. From perspective biomass utilization, paper reviews preparation methods, structural characteristics, physicochemical environmental implications biochar. The effect mechanisms on nutrients, heavy metals, organic matter in water are introduced. In light current research status, challenges faced practical application algae-derived materials pointed out, direction also developed, view providing reference further utilization
