Intensification of industrial activity, environment stress contributes to the significant rise of heavy metal pollution in water resources. Pollution due to malignant heavy metals such as lead, chromium, arsenic etc., has been tremendously focused on communal health. Lead pollution-potable water finds great threat by different sources like plating units, lead pipes etc., Newspaper is a cellulosic materials, containing cellulose, hemicellulose and other inorganic fillers. The present study evaluates the potentiality of modified newspaper pulp for sequestration of Pb(II) ions. Characterizations of loaded and unloaded pulp were evaluated by FTIR, SEM and EDAX assay. Batch experimental studies were accomplished to assess the equilibration between the sorbate-sorbent through various operating factors viz., pH, dosage, time course, initial concentration, influence of ions, co-ions and effect of temperature. The residual concentrations of the Pb2+ ions from aqueous solutions are examined by UV-Visible Spectrophotometer. The equilibrium data was appropriately fitted with Langmuir adsorption isotherm model.
