The material was characterized by FT-IR and Raman spectroscopy, thermosgravimetric and elemental analysis. The effects of pH value, shaking time, sample volume, elution conditions and potentially interfering ions were investigated. Under the optimum conditions, the maximum adsorption capacity is 38mgg−1 of Pb(II), the detection limit is 0.32ngmL−1, the enrichment factor is 60, and the relative standard deviation is 3.5% (n = 6). The method has been applied to the preconcentration of trace amounts of Pb(II) in environmental water samples with satisfactory results. Figure Oxidized multiwalled carbon nanotubes grafted with tris(2-aminoethyl)amine (MWCNTs-TAA) is prepared and employed as solid phase extraction sorbent to determinate the trace Pb(II) in water samples. The method has been applied to the preconcentration of trace amount of Pb(II) in water samples with satisfactory results.
