Abstract Efficient elimination and retrieval of phosphorus from water bodies are crucial for effective eutrophication management reuse. A novel Fe/Ca oxide co-coated modified biochar (FCBC) was synthesized phosphate recovery using coconut shell as the raw material with ferrous chloride (FeCl2) calcium peroxide (CaO2) precursors. FCBC possesses a highly intricate pore structure an abundance surface-active groups. oxides loaded onto in form Ca2Fe2O5, Fe2O3, CaCO3. demonstrates broad pH tolerance range (pH = 6 – 12) aquatic environment. Phosphorus absorption by simulated proposed pseudo-second-order kinetic Langmuir model. The maximal saturation adsorption capacity found to be 53.31 mg P/g. is influenced generation Ca3(PO4)2, intraparticle diffusion, electrostatic attraction. produced demonstrated exceptional removal effectiveness presence multiple anions, except wastewater high concentrations SO42-, CO32-, HCO3-, F- (>500 mg/L). natural samples collected ponds, farmlands, ditches exceeded 94%. This paper presents technique creating iron-calcium composite-modified biochar, which offers valuable method efficiently recovering agricultural surface waters.

Biochar can be used for multifunctional applications including the improvement of soil health and carbon storage, remediation contaminated water resources, mitigation greenhouse gas emissions odorous compounds, feed supplementation to improve animal health. A healthy preserves microbial biodiversity that is effective in supressing plant pathogens pests, recycling nutrients growth, promoting positive symbiotic associations with roots, improving structure supply nutrients, ultimately enhancing productivity growth. As a amendment, biochar assures biological through different processes. First, supports habitats microorganisms due its porous nature by formation stable micro-aggregates. also serves as nutrient source. alters physical chemical properties, creating optimum conditions diversity. immobilize pollutants reduce their bioavailability would otherwise inhibit However, depending on pyrolysis settings feedstock comprised contaminants polycyclic aromatic hydrocarbons potentially toxic elements activity, thereby impacting

Abstract Biochar-based sulfidized nano-sized zero-valent iron (SNZVI/BC) can effectively immobilize cadmium (Cd) in contaminated paddy soils. However, the synergistic effects between biochar and SNZVI on Cd immobilization, as well underlying mechanisms remain unclear. Herein, a soil microcosm incubation experiment was performed to investigate immobilization performance of SNZVI/BC towards soil. Results indicated that addition at dosage 3% significantly lessened concentration available from 14.9 (without addition) 9.9 mg kg −1 with an efficiency 33.3%, indicating effect. The sequential extraction results proportion residual increased 8.1 10.3%, manifesting transformation unstable fractions steadier specie after application SNZVI/BC. Also, pH, organic matter, dissolved carbon, which altered bacterial community soil, enriching relative abundances functional microbes (e.g., Bacillus , Clostridium Desulfosporosinus ). These microorganisms further facilitated generation ammonium, nitrate, ferrous enhancing nutrients’ availability. direct interaction 2+ physicochemical properties, responded played important roles Overall, biochar-based is promising candidate for effective improvement availability Graphical

Abstract Cd contamination, especially in farmland soil, can pose serious threats to human health as well ecological security. Stabilization is an important strategy for agricultural soil remediation. In this study, a Cd-resistant strain ( Cupriavidus B-7) was isolated and loaded onto cow manure (CDB), rice straw (RSB) pine wood biochar (PB) investigate its effects on stabilization by 60-day pot experiment. Results indicated that the B-7-loaded (labelled CDBB, PBB RSBB) reduced CaCl 2 -extractable 43.06–59.78%, which significantly superior individual applications of B-7 biochar. Likewise, physicochemical properties, urease, catalase phosphatase activities were improved, indicating improved health. Consequently, dry weights pakchoi’s shoot root increased 938.9–1230.9% 149.1–281.2%, respectively, applying RSBB. Meanwhile, accumulation pakchoi shoots decreased 38.06–50.75%. Notably, RSBB exhibited optimal performance growth promotion alleviation. The structural equation model synergistic effect between B-7. Our research provides some new insights into development strategies green sustainable remediation Cd-contaminated soil. Graphical
