    Exploitation of low cost adsorbent for purification of lead polluted water
    (University of Management and Technology Lahore, 2017) Sajjad, Tayyab
    Water is an essential component of our life. No plant, animal life should exist without water. Contamination in water is due to large number of pollutants present in it. When pollutants mixed in food it tends to be lethal across bio accumulation. Adsorption is an effective method for the purification of water from these toxic substances. Four different parameters such as effect of concentration on Pb (II) adsorption, effect of particle size on Pb(II) adsorption, effect of pH on Pb(II)adsorption and effect of temperature on Pb(II) adsorption were studied. Activated carbon having two different particle sizes 595µ and 149.6µ is used. Xylenol orange is used as complexing agent because lead forms stable complex with xylenol orange. Large surface area of activated carbon results in increasing initial lead ion concentration. When adsorbent particle size decreases density also decreases. Absorption capacity of lead is higher at pH10. Unadsorbed lead ions concentration were calculated by using UV-VIS spectrophotometer.
