Based on the comprehensive characterizations and adsorption performance, the enhancement of the metals removal by the nano ZnO/ZnS modified biochar were mainly attributed to the hydroxyl groups on the surface of nano ZnO/ZnS particles and well-developed porous structure catalyzed by zinc salt during pyrolysis process.

respectively. The above process was repeated five times, and the N-BC suspension was carefully pipetted and collected. Hydrodynamic diameters (D h) of C-BCs and N-BCs were measured by a Zetasizer (Nano ZS90, Malvern, U.K.). The extracted suspension (3 mL) was carefully moved to a quartz cuvette and examined at 800 nm (OD 800) using a UV−vis

Le biochar, une nouvelle solution écologique pour purifier les eaux usées. Le biochar, c'est une substance qui ressemble à du charbon de bois, mais qui est produite à partir de déchets agricoles.

Biochar-based nano-composites for the decontamination . Jul 01, 2016· The categories of different methods for the fabrication of biochar-based nano-materials are shown in Fig. 1.In general, these biochar-based nano-composites can be classified into the following three categories, namely, nano-metal oxide/hydroxide-biochar composites, magnetic biochar …

Nano-BC provides an optimal soil habitat for bacteria by improving soil porosity, resistance, and water holding capabilities, all of which are essential for soil activity maintenance. According to several tests, the emission of N 2 O drops by about 83% following BC modification. Additionally, biochar amendment at a rate of 1% – 2% (w/w) has ...

4. Add 15 mL concentrated HNO 3 and 45 mL concentrated H 2 SO 4 per gram of the ground biochar. 5. Static allow reaction at room temperature for 2 h in the fume hoods. 6. Transfer the mixture from the hydrothermal reactor to a beaker filled with 1000 mL deionized water, stir 1 min by glass rod and stand 10 min.

Nano biochar (N-BC) attracts increasing interest due to its unique environmental behavior. However, understanding of its formation, physicochemical characteristics, and stability of N-BC is limited. We therefore examined N-BC formation from bulk biochars (B-BCs) produced from peanut shell, cotton straw, Chinese medicine residues, and furfural ...
