原始语种摘要: Abstract(#br)A novel oxidized graphene oxide (OGO) material was prepared and employed for the dispersive solid phase extraction (d-SPE) of rare earth elements (REEs) in drinking water and nuts followed by inductively coupled plasma mass spectrometry (ICP-MS) determination. The novel material was characterized by Brunauer–Emmett–Teller (BET) surface area analysis, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transform-Infrared spectroscopy (FT-IR). Response Surface Methodology (RSM) with a Central Composite Design (CCD) and Derringer's type Desirability Function were employed for the optimization of factors that could possibly influence the extraction recovery. Response surfaces charts illustrated the effects of the...
