Dispersive micro solid-phase extraction using multiwalled carbon nanotubes for simultaneous determination of trace metal ions by energy-dispersive X-ray fluorescence spectrometry.
A methodology based on dispersive micro solid-phase extraction (DMSPE) using multiwalled carbon nanotubes (MWCNTs) as solid sorbent prior to measurement with energy-dispersive X-ray fluorescence (EDXRF) spectrometry is proposed. The procedure consists of chelating of nickel, cobalt, copper, and lead ions with ammonium pyrrolidinedithiocarbamate (APDC) and posterior adsorption of metal chelates ...
متن کاملThe Application of Multiwalled Carbon Nanotubes as Solid Phase Extraction Sorbent for Pre-concentration of Bisphenol A in Canned Food
A simple, reliable and suitable analytical method was developed for solid phase extraction of bisphenol A in several canned food products such as beverages, fruits, vegetables and foodstuffs bought in Sudan markets. The analysis done by using a packed Multi Walled Carbon Nanotubes (MWNTs) mini-column followed by highperformance liquid chromatography with fluorescence detection. In summary, we h...
متن کاملSolid Phase Extraction of Amount Cu(II) Using C18 Disks Modified Schiff Base-Chitosan Grafted Multiwalled Carbon Nanotubes
A novel and selective method for the fast determination of trace amounts of Cu(II) ions in water samples has been developed. The procedure is based on the selective formation of Cu(II) at optimum pH by elution with organic eluents and determination by flame atomic absorption spectrometry. The method is based on complex formation on the surface of the ENVI-18 DISKTM disks modified Schiff base-ch...
