Sono-assisted adsorption process is a clean, resourceful and rapid method for elimination of toxic species from water. Mesoporous zeolite Y (NaY) was synthesized from rice husk ash (RHA), using a three-step technique and then modified with iron using an ion-exchange method. As-synthesized NaY, iron-modified zeolite Y (IMZY), and commercial zeolite Y (CZY) were characterized by X-ray fluorescence (XRF) spectroscopy, X-ray diffraction (XRD) spectroscopy, Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM) equipped with an energy-dispersive X-ray spectroscopy (EDX), and Brunauer–Emmett–Teller (BET) analysis. The EDX analysis implies the presence of iron in the structure of NaY. The swift sono-assisted adsorption of As(V) from aqueous solution was compared with conventional adsorption in the presence of all three adsorbents: NaY, IMZY, and CZY. The batch sono-adsorption technique was investigated using influenced parameter...
