Comparative Study of Adsorption between Walnut and Groundnut Shell by Treating Lead (Pb II)

Abstract

Heavy metals are toxic and contaminated water pollutant. These are not only affects the human beings but also affect the vegetation and animals, because of their versatility in aqueous ecosystem. Heavy metal removal form the sewage is the most important study carried out in the field of environment. On the other hand different methods such as precipitation, membrane filtration , adsorption and ion exchange are used for heavy metals removals, adsorption procedure has fascinated towards many researchers because low cost, design efficiency and flexibility. Heavy metal (lead) removal present review focused on the performance of natural adsorbent as walnut and groundnut shell. The objective of study for the efficiency of walnut shell and groundnut shell as adsorbent for heavy metals (lead) elimination from the wastewater for batch adsorption study. The analysis was approved to identify the effect of contact time. pH and dosage for walnut shell and groundnut shell at standard temperature condition. Results showed by the maximum removal efficiency of lead and comparative study between the walnut shell and groundnut shell. The maximum removal of lead by walnut shell is 75.6% and 77.8% by ground nut shell.
