This study reveals about the importance of using an eco-friendly approach for the removal of heavy metal ions from groundwater. The potential abilities of economically cheaper natural biosorbents (Banana and Citron peels) were studied at different intervals during the removal of heavy metal ions (Copper and Lead). The two metal ions studied were copper and lead by preparing aqueous solution and also from ground water sample. The biosorption of metals was studied by various techniques such as Atomic-absorption spectroscopy (AAS) and Fourier Transform Infra-Red Spectroscopy (FTIR). From the investigation, banana and citron peels have high ability to reduce the heavy metals in which citron peels have high potential to reduce the concentration of copper in aqueous (CuS) solution, where banana peels have more ability to reduce lead concentration in aqueous (Pb(NO)3)2) solution. The percentage of removal of Cu with citron is 87.6%, Pb with banana is 79.7%. Analysis of AAS and FTIR strongly evident that banana and citron peels plays actively in the removal of heavy metals Cu and Pb in water sample also, in which the percentage of removal of Cu with citron is 72.3% and Pb with banana is 71.6%.
