Solid 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...
متن کاملCold Vapor Atomic Absorption Determination of Hg in Crude Oil and Gasoline Samples after Solid Phase Extraction Using Modified Disks
A facile and highly efficient method have been developed for the preconcentration of the mercury content in crude oil and gasoline samples after digestion with microwave-assisted digestion. Octadecyl silica membrane disk has been modified by the recently synthesized triazene ligand, (E)-1-(2-ethoxyphenyl)-3-(4-nitrophenyl) triaz-1-ene (ENT), then the modified membrane was used for the preco...

متن کاملSolid-Phase Extraction Columns for Lipid Analysis
Solid-phase extraction methods are being used for increasing numbers of applications in lipid analysis, but especially as a rapid means of isolating particular components for further analysis. Many different types of packing material are available enabling most different modes of chromatography to be used, including adsorption, reversed-phase, silver-ion and ion-exchange. However, there are occ...
