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 4.3102 for the lead ion. The detection limit was found to be 3.82 ng mL-1 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.
