Separation and Preconcentration of Anionic Dyes Using Magnetic Nanoparticles with Modify Polymer Ionic Liquid

In this study, functionalized magnetic nanoparticles of poly (ionic liquid) 1-allyl-3-methylimidazolium chloride were prepared through free radical copolymerization method and tested as a high efficient adsorbent for the removal of anionic dyes in water samples. The physical and chemical structure of prepared magnetic nanoparticles (MNPs) were investigated using Fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Next, synthesized magnetic nanoparticles were used in magnetic solid phase extraction (MSPE) method to extract three anionic dyes (Alizarin Red S, Congo Red and Methyl Orange) in water samples. Also, the effect of several parameters such as pH, temperature, contact time and amount of adsorbent was investigated and the optimum values were determined. In addition, the adsorbent has a high ability to remove anionic dyes from water samples containing different dyes. Limit of detection (LOD), limit of quantitation (LOQ), and correlation coefficient were determined for methyl orange, Congo red and alizarin red S dyes under optimum conditions. The synthesized magnetic nanoparticles can be collected by an external magnetic field and regenerated with an alkaline solution (NaOH) and reused. The obtained results showed that the MNPs@PIL method was very efficient and successful in removing dye pollutants in water samples.
