چکیده انگلیسی
Magnetic nanoparticles modified with the ionic liquid were prepared. The kinetics, adsorption isotherms, thermodynamics and spectroscopic analyses of the removal of the reactive yellow 15 by ultrasound assisted adsorption onto magnetic nanoparticles were investigated. Several variables affecting the removal of the reactive yellow 15 include amount of sorbent, pH, ultrasonic power and reaction time, salt concentration, and desorption conditions were studied and optimized. Three kinetic models were studied to analyze the adsorption mechanism. It was found that the adsorption kinetics followed a pseudo-second-order model for the dye concentration range studied in this study. Dye adsorption equilibrium data were well fitted to the Langmuir isotherm and the maximum monolayer capacity qmax was calculated from the Langmuir as 63.69 mg g−1. A thermodynamic parameter was studied by the Gibbs free energy function. The results obtained showed that the MNP modified with the IL is an appropriate adsorbent for removal of reactive yellow 15 from waste water.
