Abstract: Electrochemical industries generates a wastewater that has a potential hazard for our environment as it contains various heavy metals such as Lead, Cadmium, Nickel etc. If this wastewater left untreated, will pollute soil and water resources. Out of the above heavy metals, in this project work, only removal of Lead (Pb) from electrochemical industrial wastewater has been investigated by using low cost adsorbent such as charcoal along with coconut shell powder as a natural adsorbent. The project is a bench scale experimental type i.e. Batch mode technique and analyses have performed by using different amounts of adsorbent in solutions with different concentrations of Lead metal. Beside the effect of various amounts of adsorbent used in adsorption efficiency experiments has been investigated. Result indicates that the maximum removal efficiency for Lead is about 94% by using 0.25 gm/L amount of activated coconut shell carbon powder (ACSCP) and charcoal powder (ACP) mixed in equal amount for particular pH and contact time.

Keywords: Adsorption, batch mode technique, battery industry waste water, Coconut shell powder, Charcoal carbon powder, Economic, Heavy Metal.
