Abstract: 2-Pyridyliminosalicylcellulose has been used for the sorption and estimation of lead(II) by column and batch techniques. The distribution coefficient (D) was found to be 4.3<img src='/image/spc_char/cross.gif' border=0>10<sup>2</sup> for the lead ion. The detection limit was found to be 3.82 ng mL<sup>-1</sup> and the breakthrough volume was 20 mL. The present matrix coupled with FAAS has been used to enrich and determine the lead ions in natural and wastewater (RSD ~ 2.52-3.50%) and egg samples (RSD ~ 2.73%). The method is simple, rapid and relatively free from interference and satisfactorily applied for the estimation of lead (~98% recovery) in natural, wastewater and egg samples.
