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.

The performance of multi-walled carbon nanotubes-based filters with acid functionalization for enhanced methylene blue removal from water resources

Alexandria Engineering Journal, Journal Year: 2024, Volume and Issue: 88, P. 310 - 316

Published: Jan. 20, 2024

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.
