Biochar production under different pyrolysis temperatures with different types of agricultural wastes
Abstract The main aim of this study is to determine the physical and chemical properties of biochar synthesized from different materials (straw rice, sawdust, sugar cane, and tree leaves) at different pyrolysis temperatures (400, 600, and 800 °C). The physical and chemical properties such as moisture content, water holding capacity, bulk density, and porosity; and pH, […]

Fabrication of a bio-adsorbent material by grafting CeO2 quantum dots (QDts) over Areca nut shell biochar using Saccharum officinarum extract as a solvent/capping agent for adsorption of Methylene blue dye: Synthesis, material analyses, adsorption kinetics and isotherms studies
The presence of diverse organic compounds, such as dyes, in wastewater may pose potential environmental hazards. Therefore, it is imperative to remove these harmful substances from the various water resources. In this work, the composite of Ceria (CeO2) and areca nut shell biochar (CB) were used as adsorbents to extract Methylene blue dye (MB) from […]

Fabrication of green magnetized ferrite biochar nanocomposites from orange peels/MnFe2O4, peanut shells/CuFe2O4, tree twigs/Ni Fe2O4, and wood/CoFe2O4: characterization and application as adsorbents for adsorption/desorption/stability of basic Blue-XGRRL dye with possible mechanisms
One of the primary sources of water pollution is the wastewater released from textile industry. In the current research, green magnetized ferrite biochar nanocomposites for the purification of basic dye Blue-XGRRL were prepared and characterized. The optimal pH values to attain maximum adsorption for orange peels/MnFe2O4, peanut shells/CuFe2O4, tree twigs/Ni Fe2O4, and wood/CoFe2O4 were noticed […]

Energetic, bio-oil, biochar, and ash performances of co-pyrolysis-gasification of textile dyeing sludge and Chinese medicine residues in response to K 2 CO 3, atmosphere type, blend ratio, and temperature
Hazardous waste stream needs to be managed so as not to exceed stock- and rate-limited properties of its recipient ecosystems. The co-pyrolysis of Chinese medicine residue (CMR) and textile dyeing sludge (TDS) and its bio-oil, biochar, and ash quality and quantity were characterized as a function of the immersion of K 2 CO 3 , […]

Differential influences of forest floor-pyrolyzed biochar-derived and leached dissolved organic matter interaction with natural iron-bearing minerals in forest subsoil on the formation of mineral-associated soil organic matter
The vertical sequestration of dissolved organic matter (DOM) by iron minerals along the soil profile is assumed to be central to the long-term storage of the soil organic matter (SOM) pool. However, there is limited information available about how the interaction between DOM and natural iron-bearing minerals shape mineral SOM as-sociations quantitatively and qualitatively in […]

Screen-printed counter-electrodes based on biochar derived from wood-corn silage and titanium isopropoxide binder as a more efficient and renewable alternative to Pt-CE for dye-sensitized solar cells
Current research of counter-electrodes (CEs) for dye-sensitized solar cells (DSSCs) focuses mainly on searching for low-cost and mass-production suitable materials as an alternative to standardly used platinum. One of the most studied groups is carbon allotropes, while carbon-enriched materials such as biochar prepared from renewable sources (biomass) show tremendous potential. Structural properties of biochar, electrical […]

High removal performance of reactive blue 5G dye from industrial dyeing wastewater using biochar in a fixed-bed adsorption system: Approaches and insights based on modeling, isotherms, and thermodynamics study
In an eco-friendly context, an adsorption study was performed in a fixed-bed column system to remove organic pollutants from dyeing wastewater, testing preliminary theoretical models and reactive blue 5G (RB5G) dye as a reference pollutant and tilapia bone-based biochar as an alternative adsorbent. Adsorption approaches in removing RB5G dye molecules from synthetic solutions were performed […]

A case study of different bismuth oxyhalides BiOX (X = F, Cl, Br, and I)/ biochar-derived rice husk@graphitic carbon nitride for the robustness of H2O2 photoproduction and antibiotic photodegradation
In this study, the heterojunction photocatalyst bismuth oxyhalides/rice husk-derived biochar@graphitic carbon nitride (BiOX (X = F, Cl, Br, and I)/BC@CN) was successfully synthesized through calcination and hydrothermal self-assembly synthesis. The photo-absorption range of CN was expanded by coupling of biochar and BiOX, which also improved electron production and increased the number of active sites for […]

Comparative Study of Individual and Combined Application of Humic Acid, Wood Vinegar, and Biochar on Soil Zn Chemical Fractions and Its Uptake by Sour Orange (Citrus aurantium L.) Seedlings
The addition of organic materials in arid and semi-arid regions not only improves the physicochemical and biological characteristics of the soil but also increases plant growth. In this study, the effect of individual and combined application of humic acid (HA) (150 mg kg(-1) soil), wood vinegar (WV) (75-fold dilution), and biochars (corn straw biochar (CSB) […]

A novel oil palm frond magnetic biochar for the efficient adsorption of crystal violet and sunset yellow dyes from aqueous solution: synthesis, kinetics, isotherm, mechanism and reusability studies
This study presented a facile synthesis route via the precipitation method for the production of magnetic biochar from oil palm frond (OPF). The physicochemical characteristics including surface, functional, and magnetic properties of the synthesized magnetic biochar revealed that the surface morphology, porosity, and magnetic properties enhanced its adsorption capacity for the removal of crystal violet […]
