This review article evaluates and compares the efficiency of various sustainable adsorbents for removal noxious pollutants from water environments. study discusses types concerning their performance suitability. Adsorbent include natural-based, carbon-based, waste-based, biomass-based, biopolymers-based, nanocomposites-based adsorbents, as well metallic organic frameworks, aerogels, networking crystalline solids, zeolite nanoparticles, dendrimers were reviewed. Characterisation, modification, fabrication, adsorption capacities under different conditions, isotherm models, kinetics also Adsorption pH values, adsorbent doses, concentrations, temperature, size particles have been described. One basic needs in wastewater is formulation optimisation, using columnar operations, more importantly, they can be produced quickly should cost-effective. Various studies reported a broad range values thermodynamic parameters pollutants, suggesting adsorbent's nature an essential factor affecting thermodynamics pollutant sorption. The regeneration reusability potential other discussed, along with molecular modelling, simulation, knowledge gaps, future perspectives

Chlorinated organic pollutants constitute a significant category of persistent due to their widespread presence in the environment, which is primarily attributed expansion agricultural and industrial activities. These are characterized by persistence, potent toxicity, capability for long-range dispersion, emphasizing importance eradication mitigate environmental pollution. While conventional methods removing chlorinated encompass advanced oxidation, catalytic bioremediation, utilization biochar has emerged as prominent green efficacious method recent years. Here we review biochar's role remediating typical organics, including polychlorinated biphenyls (PCBs), triclosan (TCS), trichloroethene (TCE), tetrachloroethylene (PCE), organochlorine pesticides (OCPs), chlorobenzenes (CBs). We focus on impact material properties adsorption mechanisms organics. This highlights use sustainable eco-friendly pollutants, especially when combined with biological or chemical strategies. Biochar facilitates electron transfer efficiency between microorganisms, promoting growth dechlorinating bacteria mitigating toxicity organics through adsorption. Furthermore, can activate processes such oxidation nano zero-valent iron, generating free radicals decompose compounds. observe broader application bioprocesses treating soil, reducing impacts. Conversely, water-based integrating proved more effective, leading superior purification results. contributes theoretical practical pollutants.

The world is currently facing significant challenges in reducing the concentration of atmospheric carbon dioxide (CO2) through scientific methods, primarily by sequestering CO2 soil. Biochar a kind charcoal that composed carbon, hydrogen, and oxygen. Due to its aromatic content, biochar can persist environment for an extended period absorb greenhouse gases (GHG). Each year, effectively captures estimated amount ranging from 1 35 gigatons (GtCO2) 78 477 GtCO2 over this century. helps mitigate climate change soil periods consequently GHG emissions. This enhances fertility, water retention capacity, nutrient circulation, which promote higher crop yields. Biochar's by-products be harvested used as renewable energy source. Besides, integration effective waste management strategies organic disposal. also efficient purification element favors action. Through application alteration employed establish credits, methods reduce emissions acceptable level. unique properties, wide-spread applicability, cost-effectiveness, trustworthy development prospects demonstrate great potential towards Sustainable Development Goals (SDG). review discusses diverse applications, social technical impacts global cycle sustainable goals.

The increasing use of antibiotics induces the spread antibiotic-resistant genes (ARGs) in environment, which seriously threatens natural ecosystem and human health. Reducing environment is utmost importance. Biochar, as a cost-effective, environmentally friendly, carbon-rich porous material with circular economy prospects, has shown great potential antibiotic remediation environment. adsorption mechanisms (e.g., electrostatic interaction, hydrogen bonding hydrophobic π–π electron donor–acceptor (EDA) pore diffusion) biotic roles biochar microbial shelter, carrier, mediator) synergistically promote removal from aqueous phase. This review critically discusses various based on classes antibiotics, efficacy removal, influence crucial parameters antibiotics. Furthermore, provides critical discussion engineering application biochar. Finally, highlights prospects challenges treating antibiotic-contaminated liquid streams.

Recently, the preparation of smart multifunctional hybrid nanoparticles has captured significant interest in versatile areas, including medicine, environment, and food, due to their enhanced physicochemical properties. The present study focuses on synthesis Fe-doped NiO by coprecipitation method using sources nickel (II) acetate tetrahydrate iron (III) nitrate nonahydrate. prepared are characterized X-ray diffraction, Fourier transform infrared spectroscopy, UV–visible field-emission scanning electron microscopy, transmission photon spectroscopic analysis. XRD results clearly confirm face-centered cubic structure polycrystalline nature synthesized Fe-NiO nanoparticles. Tauc plot analysis revealed that bandgap energy decreased with increasing concentration Fe dopant from 2% 8%. XPS samples exhibited existence elements, Fe, Ni, O, absence any surplus compounds. FE-SEM TEM analyses proved formation nanostructured few spherical mostly unevenly shaped particles. Further, photocatalytic efficiency were identified cationic dye rhodamine B (Rh-B). 8% doped achieved 99% Rh-B degradation within 40 min visible-light irradiation. Hence, exemplified have acted as a noticeable photocatalyst degrade dye.

Landfill leachate (LLCH) disposal poses challenges due to high pollutant concentrations. This study investigates the use of biochar (BC) derived from wheat straw for nitrogen content reduction. Laboratory experiments evaluated BC's adsorption capacity (qm) removal ammonium chloride solution (NH4Cl) and LLCH, along with testing isotherm models. The results demonstrated that BC was more efficient (95.08%) than commercial activated carbon AC (93.11%), blank, in adsorbing NH4Cl. superior performance may be attributed its higher (57.74%) observed through elemental analysis. Lower BC/LLCH LLCH's complex chemical matrix. Langmuir model best described BC/NH4Cl (qm = 0.5738 mg/g). AC/NH4Cl data also fitted into (R2 ˃ 0.9) a qm 0.9469 mg/g, 26.667 mg/g ˂ obtained BC/LLCH; gave using Jovanovich (which follows Langmuir's assumptions). mean energy values estimated AC/NH4Cl, BC/NH4Cl, processes were 353.55, 223.61 kJ/mol, respectively, suggesting they are all chemisorption ion exchange influenced their processes. Freundlich constant (1/n) value suggests average BC/LLCH. followed Harkins-Jura (R2: 0.9992), multilayered (or mesopore filling). In conclusion, shows promising potential landfill remediation, offering capabilities demonstrating compatibility various research lays groundwork further exploration other biochar-based materials addressing environmental associated contamination.
