In this work, plasma-enhanced chemical vapor deposition method was used for synthesizing Fe₂O₃@SiO₂ thin films as a novel adsorbent for removal of heavy metal mercury(II) and hexavalent chromium ions from water samples. To that end, crystalline structure, chemical state, morphology, optical and magnetic property of deposited film were characterized using X-ray diffractometry (XRD), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), UV–vis spectrophotometer (UV–vis), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM) system respectively. Then, the effects of some parameters such as the initial pH, the initial content of metal, the synthesized adsorbent dose, the contact time, the temperature and the ionic strength were analyzed for a batch adsorption system. The adsorption data was modeled by …
