Abstract

In this work, NANOMAGNETIC HYDROGELs based on ARABIC GUM (AG) were used for removal of CRYSTAL VIOLET in aqueous solution. The hydrogels were first prepared by free radical polymerization of acryl amide (AAm) and 2-Acrylamido-2-methylpropane sulfonic acid (AMPS) in the presence of ARABIC GUM using N,N′-methylenebis (acrylamide) (MBA) as a crosslinker agent and ammonium persulfate (APS) as an initiator. Then, nanocomposite hydrogels were prepared via in situ reduction of loaded Co2+ ions by using sodium borohydride. The effect of different variables, such as contact time, initial concentration of dye, temperature, and pH of solution, were investigated on the sorption behavior of the CRYSTAL VIOLET. The structure of the hydrogels was characterized by FT-IR spectroscopy, thermal gravimetric analysis (TGA), and scanning electron microscopy (SEM). The results of scanning electron microscopy show that the magnetic nanocomposite has a good dispersion in the hydrogel matrix and the approximate size of the particles are about 10-30 nm. The results of this study show that the NANOMAGNETIC HYDROGELs with high removal efficiency and low reaction time can be used as effective adsorbents for the removal of CRYSTAL VIOLET dyes from aqueous solution. The adsorption isotherm show that the adsorption of CRYSTAL VIOLET on the nanocomposite hydrogels follow the Temkin adsorption model.
