Abstract

The removal of Pb (II) from aqueous solutions by chitosan coated saw dust activated carbon (CCSDAC) was
investigated. The higher percentage removal of Pb (II) from aqueous solutions in the presence of saw dust activated
carbon (SDAC) and CCSDAC was observed. The later adsorbent (CCSDAC) has the higher percentage removal than
that of the former (SDAC). The mechanism of adsorption was studied by conducting pH as well as kinetic studies.
Batch adsorption experiments were conducted to study the effect of adsorbent dose, initial concentration and
temperature on the removal of Pb (II) using SDAC and CCSDAC. When compared to SDAC, CCSDAC has higher
adsorption at pH 4.0. The kinetic and equilibrium adsorption datas were well modeled using pseudo-first- order
kinetic and Langmuir isotherm models.
