Abstract:	A viable and cost-effective technology was explored in this present task for removal of heavy metal ions Such as Cu(2+), Ni(2+), Zn(2+), Cd(2+), and Pb(2+) from aqueous Solution using three fruit peels Such as orange peel (OP), lemon peel (LP), and banana peel (BP). The surface of the LP and lemon peel cellulose (LPC) was chemically modified. All these adsorbents were characterized by FT-IR, BET, and SEM. The widely used Langmuir adsorption isotherms were used to describe the adsorption equilibrium process. The adsorption capacity of metal ions Such as Cu(2+) and Ni(2+) Was found to be more than that of other metal ions. Upon comparison of the adsorbents, surface modified LPC (LPCACS) was found to show enhanced adsorption activity. A comparative Study of adsorption was carried Out with activated carbon (AC) also from which it was inferred that the order of the adsorption capacity is as follows: LPCACS > LPC > AC > LP.
