“…In contrast with this, Ajmal et al (2000), Qin et al (2012), Zou et al (2012), and Hafeez et al (2010) found the endothermic nature on adsorption. In this case, the adsorption capacity of FPW increases with an increase in temperature.…”

“…The physico-chemical parameters of different isotherms, together with the fundamental thermodynamic assumptions, help to understand the adsorption mechanism, the surface properties of the adsorbate, and the degree of affinity (Ho et al 2002, Behnamfard and Salarirad 2009, Foo and Hameed 2010Tümsek and Avcı 2013). FPW batch adsorption data for different systems have been fitted to a wide variety of equilibrium isotherms, like Langmuir, Freundlich, Sips, Redliche-Peterson, Temkin, Dubinin-Raduskevich, Dubinine-Kaganere-Radushkevich, Toth, Koble-Corrigan, Harkins-Jura, Flory-Huggins, ion exchange, generalized isotherm, Langmuir-Hinshelwood, and BET, and used for modeling FPW-adsorption systems data (Perez-Marın et al 2007, Khaled et al 2009a, Marín et al 2009, Khaskheli et al 2011, Foo and Hameed 2012, Zou et al 2012.…”

AbstractFruit peel waste (FPW) is abundantly available from the agricultural and food processing industry and has been studied in recent past as an adsorbent. This paper critically reviews the reported work and investigates various FPW-pollutant systems. The study includes statistics of FPW generation, modification, characterization, adsorption ability, recovery/regeneration, and modeling (isotherms, kinetics, and thermodynamics) of batch adsorption. It is found that orange and banana peels are the most extensively studied adsorbents, whereas Pb

Characterizing Fruit and Vegetable Peels as Bioadsorbents

Fruit and vegetable peel (FVP) wastes are a commonly generated organic waste from both households and food-processing industries. However, FVPs are lowcost lignocellulosic materials that have some potential for reutilization. For its particular reutilization, the characterization of FVP is essential. In this regard, the present study provides a detailed physico-chemical characterization of commonly used FVPs such as pomegranate, pineapple, watermelon, garlic, green pea and pigeon pea. The materials were characterized by SEM, FTIR and TGA/DTG. Various properties of these materials, such as porosity, particle density, bulk density, surface charges, point of zero charge, surface pH, water absorption capacity and BET surface area were determined. The BET surface area of FVP was found in the range 1.0-1.4 m 2 /g. Water absorption capacity was highest for watermelon peel (11.5 ml/g), while it was lowest for pigeon pea peel (5.5 ml/g). Point of zero charge and surface pH of all FVPs were in the acidic range 3-6. The surface of FVP was irregular and rough with some pores. Thermal analysis showed that FVPs are thermally stable below 150C. The results of this study provide an understanding of the properties of FVPs and suggest that the materials can be used as a low-cost adsorbent.
