Removal of lead from waste water using lantana camara as adsorbent

Abstract

As we are moving towards the development by urbanization and industrialization on the other hand it is becoming a major environmental impact. Due to the urbanization and industrialization, many processing industries causing major environmental problem, among these problems heavy metal pollution by allowing of industrial waste water into natural water bodies is more dreadful. This is turn increase the heavy metal concentration in natural water bodies resulting in damage to aquatic flora and fauna. The objective of this study is to determine the heavy metal concentration (i.e. Pb) in industrial waste water, in this project waste water from one of the electroplating industries in Bangalore; this study gives knowledge about the percentage removal of lead using lantana camara as an adsorbent. The optimum condition for effective removal of lead is studied by conducting various experiments by varying adsorbent dosage and agitation time and by plotting isotherms, i.e. langmiur isotherms and Freundlich isotherms and pseudo I order and pseudo II order kinematics. This study is carried out using spectrophotometer analysis.
