The frequent use of an industrial dye such as malachite green (MG) has caused major water body deterioration and is one the most pressing global challenges, demanding effective treatment techniques. To solve these issues, a simplistic method was developed to synthesize zinc-tungstate (ZnWO4) nanoparticles also dope surface matrix ZnWO4 using nonmetals boron (B), carbon (C), nitrogen (N) at different ratios for enhanced MG removal from wastewater. prepared nanomaterials were characterized by methods crystal structure composition, properties, morphology, microstructures, functional groups, elemental oxidation states. BET analysis revealed mesoporous with areas 30.740 m2/g ZnWO4, 38.513 ZnWO4@BCN, 37.368 ZnWO4@BCN/B, 39.325 ZnWO4@BCN/C, 45.436 ZnWO4@BCN/N nanocomposites. best accomplished pH (8), contact period (50 min), nanoadsorbent dose (0.8 g/L), initial concentration (20 mg/L), temperature (303 K). maximum adsorption capacities towards 218.645 251.758 mg/g, respectively. At equilibrium, Freundlich isotherm pseudo-second-order kinetic models fits experimental data on both nanoadsorbents. After eight cycles desorption, found be good removing MG, efficiencies 71.00 74.20%, Thermodynamic investigations further validated spontaneity endothermic nature process. All study findings confirm nanoadsorbents exceptional capability economic feasibility dye.

In the current investigation, functionalization of multiwalled carbon nanotubes (MWCNTs-TMD) is conducted to enhance adsorption potential applications. A ratio 1:3 oxidizing acids (HNO3 and H2SO4) used attach oxygen functional groups surface MWCNTs prepared sample F-MWCNT. To examine morphology functionalized tubes in samples, transmission electron microscopy scanning were utilized. Meanwhile, energy dispersive X-ray, X-ray diffraction analysis employed account for elemental composition structure, respectively. The data obtained from these investigations revealed a notable decrease length diameter tubes. efficiency F-MWCNTs was examined by methylene blue removal aqueous solutions. results demonstrated that percentage could reach 80%. Functionalized have greater area than pristine one, which improves MWCNTs-based filters water purification. process provides an effective approach modify significantly enhances their efficiency.

The rise of antibiotic pollutants in water threatens ecosystems and human health. Iron-modified biochar (BC) exhibits adsorption properties offers a promising approach for effective environmental remediation. current study explored the potential iron-loaded synthesized from pine cones removal water. In this study, cones, sustainable renewable source, were used to produce iron-modified employed remove azithromycin, ciprofloxacin, their mixture aqueous solutions. Biochar was through pyrolysis modified by addition iron salts. analysis Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM) suggested crystalline structure rich minerals functional groups (O–H, C=O, C≡C) loaded with iron, having plate-like roughness distorted morphology along sharp edges corners. Antibiotic evaluated changing physical parameters, including dose, pH, temperature. maximum percentages obtained as 87.8%, 91.3%, 84%, respectively, at low Fe-modified higher Application kinetic models that antibiotics on is more inclined toward pseudo-second-order ( R 2 > 0.98) kinetics, indicating chemisorption nature process. findings highlight removing

This study presents a novel approach for the production of cellulosic fibers from scots pine wood and their subsequent surface modification with greenly synthesized silver nanoparticles (AgNPs), leading to remarkable color effects improved functionalities, particularly enhanced thermal stability. The size distribution fiber (SPF)materials was determined through sieve analysis, revealing conversion particles 1.25 mm 0.8 in size. AgNPs were biosynthesized situ on using same as sustainable stabilizing reducing agent. Scanning electron microscopy (SEM) employed investigate morphologies control AgNP-deposited samples, indicating uniform nanosilver coated surfaces SPF material. concentration quantitatively measured X-ray fluorescence (XRF) tests, ranging 4149 ± 43 6329 55 parts per million (PPM) depending AgNP concentration. weight percentage by SEM-mediated energy-disruptive (EDX) analysis. Additional analyses, Fourier transform infrared spectroscopy (FTIR) test also conducted.
