Removal Performance of Methyl Blue Onto Magnetic MgFe2O4 Nanoparticles Prepared via the Rapid Combustion Process
A rapid combustion process for the preparation of magnetic MgFe2O4 nanoparticles was introduced; the structure and properties of the as-prepared product were investigated by XRD, SEM, TEM and VSM techniques. The experimental results revealed that the volume of
absolute alcohol and the calcination temperature were two key parameters for the preparation of MgFe2O4 nanoparticles. With the volume of absolute alcohol increasing from 10 mL to 25 mL, the particle size of MgFe2O4 nanoparticles decreased from 70
nm to 52 nm; while with the calcination temperature increasing from 400 °C to 800 °C, the particle size was increased from 52 nm to 123 nm. The magnetic MgFe2O4 nanoparticles calcined at 400 °C for 2 h were characterized with the average particle size of around
50 nm and the specific magnetization of 247.2 Am2/kg. The magnetic MgFe2O4 nanoparticles were employed to remove methyl blue (MB) from aqueous solution, the adsorption kinetics and adsorption isotherm of MB onto MgFe2O4 nanoparticles at
room temperature were investigated, and the regression equation was found in good agreement with the pseudo-second-order model in the initial MB concentrations of 100–400 mg/L; the adsorption equilibrium data of MB onto MgFe2O4 nanoparticles at room temperature
were analyzed with Langmuir, Freundlich and Temkin models, and the adsorption isotherm was more effectively described by the Temkin model based on the value of the correlation coefficient (0.9981).
