Abstract

The current study focus on the performance of Azadirachtaindica (Neem) as a bio-adsorbent used for the removal of lead from polluted water, among various pollutants lead is the major pollutant in water. Conventionally theremoval of lead is carried out using chemical treatments. In the present research work the main aim is to remove Pb (lead) from polluted water using Neem powder. After literature review, we have selected Azadirachtaindica (Neem) which can be effectively used for the removal of lead from polluted water. Study was carried out with variation in contact time, variation in dosage and variation in concentration of bio- adsorbent. The sample of polluted water were tested using atomic adsorption spectroscopy (AAS-7000) for initial concentration of lead varied from 0.5-2 ppm, optimum results were obtained with 210 minutes contact time for dose of 50 mg/lit gives maximum removal efficiency of 97.80%. Similarvalues wereobtained for 0.5, 1, 1.5 and 2 ppm initial concentration of lead with removal efficiency 97.80 %,81.20%, 76.50 %, and 74.10% for 210 minutes contact time.
