Abstract

In the current study, CdS/ZnS core–shell nanoparticles were successfully synthesized from CdSO4·8H2O and Zn(NO3)2·6H2O starting reagents in the presence of ultrasonic irradiation. The effects of preparation parameters such as ultrasonic power, irradiation time, and precursor concentration on the morphology of the CdS/ZnS core–shell nanoparticles and the removal of heavy metals (Hg+2, Pb+2) were studied by SEM and batch adsorption studies. The as-synthesized products were characterized by powder X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution field-emission transmission electron microscopy (HRTEM), photoluminescence spectroscopy (PL), scanning electronic microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and ultraviolet-visible (UV-Vis) spectroscopy.
