Abstract
The magnetic solid-phase extraction, based on the adsorption of 1-(2-pyridylazo)-2-naphthol as ions exchange groups onto magnetite nanoparticles (Fe3O4 nanoparticles) to form modified magnetic nanoparticles, was proposed for the preconcentration of cobalt and nickel from urine samples by graphite furnace atomic absorption spectrometry (GFAAS). Various parameters affecting the adsorption of cobalt and nickel were investigated, such as pH of the solution, type, volume and concentration of desorbing reagent, amount of adsorbent and interference effects. Under the optimum conditions, the calibration graphs were linear in the range of 10-50 and 10-60 ng L-1 with detection limit of 2.5 and 3 ng L-1 for cobalt and nickel, respectively. A good relative standard deviation for 10 determination of 20 ng L-1 of cobalt and nickel were 3.85 and 4.25 %, respectively. The proposed method was applied to the analysis of four urine samples with satisfactory results.
