Abstract :
    A simple and sensitive method for preparation of the adsorbent and solid phase extraction procedure for multi-element determination by inductively coupled plasma mass spectrometry (ICP-MS) has been proposed. The magnetic solid phase extraction (MSPE) was synthesised by Chemical co-precipitation method. Cd(II), Ni(II) and Pb(II) were quantitateively (Fe3O4) recovered using Fe3O4 from aqueous solutions at pH 6.7 and at a flow rate of 1.0 mL min−1 . All the elements can easily be eluted by 3.0 mL 0.3 M HNO3. A mini-column packed with 0.15 g Fe3O4 retained all elements quantitatively from up to 50 mL multi-element solution. The relative standard deviation for five replicate determinations was 5.7% and 4.1% and 4.8%, for Ni(II), Cd(II), and Pb(II) respectively, for determination of 10 μg L−1 level. The developed method was applied for SPE-ICP-MS determination of Cd, Ni, Pb, in groundwater and snow.
