Removal of Crystal Violet and Eriochrome Black T Dyes from Aqueous Solutions by Magnetic Nanoparticles Biosynthesized from Leaf Extract of Fraxinus Chinensis Roxb

Efficient removal of Eriochrome black-T from aqueous solution using NiFe2O4 magnetic nanoparticles

The magnetic NiFe2O4 nanoparticles have been synthesized and used as adsorbents for removal of an azo dye, Eriochrome black-T (EBT) from aqueous solution. The NiFe2O4 nanoparticles were characterized by scanning electron microscope (SEM), Transmission electron microscope (TEM), X-ray diffraction (XRD) and Fourier transform infrared spectra (FTIR). The adsorption studies were carried out under v...

Application of Magnetic-modified Fe3O Nanoparticles for Removal of Crystal Violet from Aqueous Solution: Kinetic, Equilibrium and Thermodynamic Studies

The prepared magnetic-modified Fe3 O4 nanoparticles (Fe3 O4 -TAN) were used as adsorbent for removal of crystal violet (CV) from water solution. The effects of pH, contact time, dye concentration and temperature on adsorption were determined. The experimental data were analyzed using the Langmuir adsorption model. The data fitted well to the model with maximum adsorption capacities 84.0 mg/gund...

Montmorillonite Nanoparticles in Removal of Textile Dyes from Aqueous Solutions: Study of Kinetics and Thermodynamics

Dyeing wastewaters are one of the most common pollutants that cause many problems for public health and environment due to dermatitis and skin rashes, cancer production, mutagenesis, etc. Thus, treatment of these wastewaters is necessary. The purpose of this study was to investigate the efficiency of montmorillonite nanoparticles as an adsorbent in adsorption process of Reactive Ye...
