Abstract

In recent years, environmental pollution with heavy metal has attracted the attention of many research groups worldwide. Contamination with these heavy metal has also increased public concerns because of their toxicities in relatively low concentration, their non-biodegradable nature and tendency of bioaccumulation. The increasing demand for the recovery of these metals from industrial effluents has stressed the development and the testing of new sorbing materials including use of abundant waste biomaterials. For last three to four decades, biopolymers have been extensively studied because of their interactions with metal ions. In this project, it is going to remove the lead metal from electroplating industrial waste water which was collected from an electroplating industry at Ambattur Industrial Estate, Ambattur, Chennai. Here, the adsorbent used is Chitosan, a Bioadsorbent in this project. Chitin is the main structural component of the exoskeleton of crustaceans (e.g., crabs, prawns, crabs, insects and shrimps) and the cell walls of fungi. Chitin is a polymer made up of acetylglucosamine units. In the case of some Mucorales species, chitin is replaced by chitosan, a polymer made up of glucosamine units.
