This synthetic route involved the reaction of 5\u2010mercapto\u20101\u2010methyl\u20101\u2010H\u2010tetrazol with 3\u2010chloropropyltriethoxysilane, prior to immobilization on the support. The resulting material has been characterized and employed as solid phase extractant for Pb(II). The effect of several variables (stirring time, pH, temperature, metal concentration, presence of other metals) has been studied using batch and column techniques. In batch experiments, 15 min stirring time, 55\u00b0C and pH 8 were the optimal conditions for Pb(II) adsorption. In column experiments, sorption was quantitative for 1000 mL of 2.41\u00d710<jats:sup>\u20134 <\/jats:sup>mM of Pb(II) solution and adsorbed ions were eluted out by 5 mL of 1 M HCl (preconcentration factor of 200). Spiked tap water was used for the preconcentration and determination of Pb(II) by flame atomic absorption spectrometry, and a 100% recovery was obtained. The LOD and LOQ values of the proposed method were found to be 3.52\u00d710<jats:sup>\u20133<\/jats:sup> and 4.20\u00d710<jats:sup>\u20133 <\/jats:sup>mM, respectively. The RSD for three preconcentration experiments was found to be \u2a872%.
