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.

Textural properties and adsorption behavior of Zn–Mg–Al layered double hydroxide upon crystal violet dye removal as a low cost, effective, and recyclable adsorbent

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: April 20, 2023

The preparation of adsorbents plays a vital role in the adsorption method. In particular, many with high specific surface areas and unique shapes are essential for strategy. A Zn-Mg-Al/layer double hydroxide (LDH) was designed this study using simple co-precipitation process. Adsorbent based on Zn-Mg-Al/LDH used to remove crystal violet (CV) from wastewater. impacts initial dye concentration, pH, temperature CV performance were systematically examined. analyzed both before after FTIR, XRD, SEM. roughness parameters morphologies produced LDH estimated 3D SEM images. Under best conditions (dose adsorbent = 0.07 g pH 9), maximum capacity has been achieved. Adsorption kinetics studies revealed that reaction led onto pseudo-second-order model. Additionally, intraparticle diffusion suggests fast constant molecules (0.251 mg/(g min1/2)). Furthermore, as predicted by Langmuir model, maximal 64.80 mg/g. dimensionless separation factor (RL) 0.769, indicating favorable. effect performed at 25, 35, 45 °C order establish thermodynamic ∆Ho, ∆So, ∆Go. computed values indicated exothermic spontaneous processes. presented here might be develop new enhanced capabilities purpose protecting water environment.

Adsorption mechanism and modeling of radionuclides and heavy metals onto ZnO nanoparticles: a review

Applied Water Science, Journal Year: 2022, Volume and Issue: 13(1)

Published: Nov. 27, 2022

Abstract The contamination of environmental waters with heavy metals and radionuclides is increasing because rapid industrial population growth. removal these contaminants from water via adsorption onto metal nanoparticles an efficient promising technique to abate the toxic effects associated pollutants. Among nanoparticle adsorbents, zinc oxide (ZnONPs) have received tremendous attention owing their biocompatibility, affordability, long-term stability, surface characteristics, nontoxicity, powerful antibacterial activity against microbes found in water. In this review, we considered ZnONPs. We examined isotherm, kinetic, thermodynamic modeling process as well mechanism provide significant insights into interactions between pollutants nanoparticles. ZnONPs areas (3.93 58.0 m 2 /g) synthesized by different methods exhibited capacities (0.30 1500 mg/g) for Langmuir Freundlich isotherms were most suitable process. separation factor indicated favorable all on pseudo-second-order kinetics presented best adsorbates regression values range 0.986–1.000. Spontaneous was obtained studies involving endothermic exothermic processes. complexation, precipitation, ion exchange, electrostatic are probable mechanisms a predominance complexation. desorption process, reusability direction future investigations also presented.
