Chemical Vapour Deposition of MWCNT on Silica Coated Fe₃O₄ and Use of Response Surface Methodology for Optimizing the Extraction of Organophosphorus Pesticides from Water.

ABSTRACT: Multiwalled carbon nanotube (MWCNT) was fixed onto the surface of a magnetic silica (Fe₃O₄@SiO₂) substrate via chemical vapour deposition (CVD). Acetylene gas was used as the carbon source and cobalt oxide as the catalyst. The chemical and physical characteristics of the materials were investigated by transmission electron microscopy (TEM), Raman spectroscopy (RS), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), X-ray diffraction (XRD), and nitrogen adsorption/desorption isotherm. The synthesized Fe₃O₄@SiO₂-MWCNT nanocomposite was used as a magnetic solid phase extraction (MSPE) adsorbent for the preconcentration of organophosphorus pesticides (OPPs), specifically, azinphos methyl, chlorpyrifos, par
