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.
