Green synthesis of iron oxide nanoparticles by Taguchi design of experiment method for effective adsorption of methylene blue and methyl orange from textile wastewater

Results in Engineering, Journal Year: 2023, Volume and Issue: 19, P. 101198 - 101198

Published: June 1, 2023

Since the beginning of industrial revolution, uncontrolled discharge wastewater from textile and dyeing industries into water bodies is environmentally challenging to humans ecosystem. Using Cola nitida (CN) leaves extract, Taguchi optimization method was successfully applied achieve green synthesis iron oxide nanoparticles (CN–Fe2O3NPs). Textural properties, nature surface functional groups, crystalline structure morphology CN–Fe2O3NPs were studied. The performance tested for methylene blue (MB) methyl orange (MO) removal wastewater. optimal area 125.31 m2/g achieved using CN extract volume (10 mL), precursor concentration (2 M), contact time (30 min) calcination temperature (600 °C). Overall, had highest effect than other parameters. characterization revealed presence hematite with Fe–O, Fe–O–Fe groups a regular-shaped porous material. Furthermore, adsorption capacity 530.406 527.835 mg/g obtained MB MO within 60 min nanoadsorbent dosage (25 mg/L), initial dye (100 mg/L) (50 reusability stability successful reuse after six cycles without any damage as corroborated by fourier transform infrared (FTIR) spectroscopy. experimental data suitably fitted Langmuir isotherm pseudo-second-order kinetic models denoting chemisorption monolayer process. thermodynamic parameters indicate an endothermic spontaneous Hence, high separation effectiveness against molecules good great potential synthesized in purification.

Magnetic adsorbents for removal of pharmaceuticals: A review of adsorption properties

Journal of Molecular Liquids, Journal Year: 2023, Volume and Issue: 384, P. 122174 - 122174

Published: May 25, 2023

The global development of industry and agriculture around the world led to contamination various aquatic environments with pharmaceuticals. Even at low concentrations in water, these pollutants cause significant human health problems, adversely affect quality drinking have a detrimental effect on environment. uncontrolled release pharmaceuticals into ecosystems poses real threat all life Earth requires effective methods removal. Adsorption is one best most cost-effective ways clean wastewater from micropollutants. Magnetic adsorbents attract considerable attention due their outstanding magnetic properties, high surface reactivity, chemical stability, possibility modification functionalization. presence functional groups makes it possible increase adsorption efficiency. This article comprehensive review studies use nanoparticles composites for removal aqueous through adsorption. main paid two categories pharmaceuticals: antibiotics (tetracycline, ciprofloxacin, levofloxacin, etc.) nonsteroidal anti-inflammatory drugs (diclofenac, ibuprofen, etc.). concentration European waters provided. modes interaction between adsorbent (functionalized nanoparticles) adsorbate (pharmaceuticals) are discussed. analyzed mainly adsorbed electrostatic interactions, hydrogen bonds, π-π interaction, complexation, ion-exchange, etc. parameters (pH, contact time, temperature, concentration, dose) efficiency summarized. analysis shows that behavior strongly depends solution pH, initial pollutant. functionalized good potential media. perspectives problems applications been presented.
