Removal of Pb(II) from Aqueous Solution Using Composite Filter Material Made of Fly Ash

Abstract:

Adsorption of Pb(II) on composite filter material mainly made of fly ash was investigated for the removal of Pb(II) from aqueous solution. Batch experiments have been carried out for adsorption of Pb(II) on to this composite filter material. The effects of various parameters influencing the Pb(II) adsorption such as contact time, initial pH, different dosage of adsorbent and temperature have been studied. Results showed that adsorption equilibrium attained within 60 minutes time. Increase in adsorbent dosage led to increase in Pb(II) adsorption due to increased number of adsorption sites. Adsorption process was found to be highly pH dependent, and the optimum pH range for adsorption of Pb(II) was found to be >8.5. The sorption of Pb(II) increased with rise of temperature.
