FIXED BED ADSORPTIVE REMOVAL OF Pb (II) IONS FROM AQUEOUS SOLUTION USING ACTIVATED CARBONS

摘要

Lead treatment and recovery plants, paint and ceramic industries discharges lead as an effluent on the surface which then find its way to surface water. It forms complexes in human body and interfere with several body processes. Lakshmi and Srinivasan, Kanan and Raj observed that the Pb uptake increased with increase in agitation time, dose and initial pH. Some other workers investigated the equilibrium adsorption of pb(II)ions and found that it depends on the pH of the solution and the surface acidity of the carbon surface. The dynamic studies were carried under varying conditions of pH, the bed depth and concentration of Pb(II) ions in the solution.
