Abstract

In this paper, a new method for preconcentration and measurement of trace amounts of Nickel in aqueous samples by Magnetic Solid Phase Extraction (MSPE) via Magnetic Carbon Nanotubes (Mag-CNTs) was developed. In order to increase selectivity, Y-Furildioxime was used as chelating agent. In order to do extraction, optimum amount of ligand was added to the Nickel sample and pH was set on 9, then 7 ml. of adsorbent was added and stirred for 15 minutes. After that, aqueous phase and adsorbent were separated by a strong magnet. Finally, the absorption was measured via flame atomic absorption spectrometry by analyte elution from the absorbent with an appropriate solution. Parameters affecting the extraction and preconcentration of Nickel were investigated and optimized. Under optimum conditions, the calibration curve was linear in concentration range from 2. 5 to 375 Zg L-1 and the detection limit was 0. 8 Zg L-1 of Nickel. The method was applied for determination of Nickel in aqueous samples. The relative efficiency values of Nickel measurement in aqueous samples were from 98. 7% to 102. 1%. Results indicated that Mag-CNTs can be used as an effective and inexpensive absorbent for preconcentration and extraction of Nickel from actual samples.
