Inductively coupled plasma optical emission spectrometry was used for detection. The effects of pH, shaking time, sample flow rate and volume, elution condition and interfering ions were examined using batch and column procedures. An enrichment factor of 100 was accomplished. Common other ions do not interfere in both the separation and determination. The maximum adsorption capacity of the sorbent at optimum conditions is 60.3mgg−1 of Pb(II), the detection limit (3σ) is 0.27ngmL−1, and the relative standard deviation is 1.6% (n = 8). The method was validated using a certified reference material, and has been applied to the determination of trace Pb(II) in water samples with satisfactory results. Figure 2-Aminobenzothiazole modified multiwalled carbon nanotubes has been developed to separate and concentrate trace Pb(II) from aqueous samples. Parameters that affect the sorption and elution efficiency were studied in batch and column modes, and the new sorbent (MWCNTs-ABTZ) presents high selectivity and adsorption capacity for the solid phase extraction of trace Pb(II).
