Application of Copper Vanadate Nanoparticles for Removal of Methylene Blue from Aqueous Solution: Kinetics, Equilibrium, and Thermodynamic Studies

Copper vanadate nanoparticles were synthesized by a simple coprecipitation method in an aqueous medium and the products were used as adsorbents for eliminating methylene blue (MB) from water. The structure and morphology of the produced nanoparticles were evaluated through X-Ray Diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM) analysis. The results...

Application of the Modified Biochar from Sewage Sludge for Removal of Pb(II) from Aqueous Solution: Kinetics, Equilibrium and Thermodynamic Studies

An adsorbent Modified Biochar (MB) made from sewage sludge was characterized with FT-IR spectra and SEM image. The effects of contact time, solution temperature, pH and initial concentration on the adsorption performance Pb(II) onto MB was investigated in a batch adsorption experiment. Results showed that MB had great adsorption capacity, due to the existence of hydroxyl, carboxyl, ether, alcoh...

Removal of Crystal violet Dye from Aqueous Solution Using Surfactant Modified NiFe2O4 as Nanoadsorbent; Isotherms, Thermodynamics and kinetics Studies

The removal of crystal violet from aqueous solution by NiFe2O4 magnetic nanoparticles treated with sodium dodecyl sulfate was investigated. The modified magnetic nanoparticles were prepared by chemical reaction of a mixture of Ni+2 and Fe+3 ions mixture in aqueous solution at the presence of ammonia and then sodium dodecyl sulfate was utilized as an ionic surfactant to modified the obtained mag...

Adsorption of Malachite Green from Aqueous Solution by Nanozeolite Clinoptilolite: Equilibrium, Kinetic and Thermodynamic Studies

The object of present study was to examine the adsorption potential of nanozeolite clinoptilolite (CP) for the removal of malachite green (MG) from aqueous phase in a batch equilibrium system. SEM, EDX, XRF, XRD and FT-IR techniques of characterization of zeolite were applied. The effects of initial pH solution, adsorbent dose, temperature, contact time and initial MG concentration on adsorptio...
