Fruit wastes are generated as a by-product of food industry in large quantities that their deposition in landfills causes environmental problems. Therefore, recycling of these wastes is very important.Since these wastes are cheap, renewable, available and producible in large amount and their sources are quickly restored, their conversion into the biochar and their application as heavy metal sorbents from wastewater, are important in view of economical and environmental aspects. In this study, the peelwastes of pomegranate, orange and lemon were collected from various fruit juice factories and were converted into biochar using slow pyrolysis at 300, 400 and 500° C under nitrogen atmosphere for one hour. Then, their ability to remove lead (Pb) and zinc (Zn) from aqueous solutions in a batch experiments was investigated separately. The results showed that the biochar derived from orange peel in temperature of 500° C (OP-BC), biochar derived from pomegranate pell in temperature of 500° C (PP-BC) and biochar derived from lemon peel in temperature of 400° C (LP-BC) had the most ability for removal of Pb and Zn from aqueous solutions. The properties of biochar samples were characterized usingFT-IR spectroscopy, BET and SEM analyses. Although the samples had relatively low surface area (0.38-1.00 m 2 /g), they showed a high ability for removal of Pb from aqueous solutions. FTIR spectroscopy described the major function groups on the surface of biochars. The results revealed the presence of carboxyl, hydroxyl, and carbonyl groups, which were likely responsible for the adsorption of Pb and Zn ions. The N 2 adsorption–desorption isotherms indicated type III isotherm for three biochar samples. In this study the effect of initial concentrations of Pb (10, 25, 50, 100 and 200 mg/L) and Zn (1, 5, 10, 100 and 200 mg/L), dose of biochar (1, 5, 10, 20 and 30 g/L), contact time (5, 15, 30, 60 and 120 min) and pH solution (2, 3, 4, 5, 6) were investigated using Taguchi design experiments. Based on the results, initial concentration of Zn was the most important factor for optimization process of Zn sorption, while dose of biochar had the greatest effect for Pb. Although, the contribution of various factors in absorption of Pb and Zn for all samples was not same, the least significant factor for them was contact time. The optimum conditions for Pb sorption of three biochar samples were initial concentration of Pb=100 mg/L, dose of biochar=30 g/L and pH of solution=6, which resulted in 95% removal efficiency of Pb. The optimum conditions for Zn sorption of the samples was initial concentration of Zn=1 mg/L, dose of biochar=30 g/L and pH of solution=5, that in this condition removal efficiency of Zn was 97%. The equilibrium data were well ?tted with Freundlich model and the adsorption process was well described by pseudo-second-order model. Keywords: Adsorption, Biochar, Fruit wastes, Heavy metals
