“…Peaks below 1000 cm À1 have been attributed to such groups as aromatic CAH bending vibrations (874 cm À1 ), thioesters (672 cm À1 ), but majorly plane deformations. Similar observations have been reported by Yan et al [4], Pehlivan et al [6], Chakravarty et al [27] and Yao et al [28].…”

“…1). These shifts may be attributed to the counter ions changes associated with the respective functional groups anions when they act as proton donors, suggesting their participation in Pb 2+ ion adsorption [4,6,27]. No marked change in frequency was observed between both spectra in the region just below 3000 cm À1 (hydroxyl functional groups).…”

However, some major limitations of these biosorptions are that some of them have not yielded satisfactory results (high metal adsorption capacity) and others that yielded good results may not locally be available.…”

Equilibrium isotherms, kinetics and thermodynamic parameters have been evaluated. The FT-IR analysis showed that likely functional groups responsible for the adsorption are carboxyl, carbonyl, amides and hydroxyl groups. The pH for optimum adsorption is 5.0. Equilibrium data fit well to the Langmuir isotherm. The estimated maximum adsorption capacity was found to be 62.50 mg/g at 298 K and 90.91 mg/g at 323 K. The kinetic data obeyed the pseudo-second-order model. The free energy changes (DG o ) are positive and the reaction is exothermic with decreased randomness at the sorbent/solution interface. Taking into account its good adsorption capacity, ease of sample treatment, as well as availability, the biomass of B. lambarenensis is a promising cost-effective biosorbent for Pb 2+ removal from aqueous environment.

“…Shells consist of cellulose, hemicellulose and lignin. Cellulose is a common material in plant cell walls and lignin is relatively hydrophobic and aromatic in nature (Pehlivan et al 2009). Dolas et al (2011) reported that activated carbon having high surface area were produced from pistachio shells that were chemically activated using ZnCl 2 at room temperature and then activated in carbon dioxide gas that was saturated in water vapor.…”

At present, there is growing interest in using low cost, commercially available materials for the adsorption of heavy metals. The major advantages of adsorption technologies are its effectiveness in reducing the concentration of heavy metal ions to very low levels and the use of inexpensive adsorbent materials. In this review, agricultural and forest waste adsorbents were used to remove Pb 2? ions in wastewater treatment, and their technical feasibilities were reviewed in studies mainly from 2000 to 2010. They all were compared with each other by metal binding capacities, metal removal performances, sorbent dose, optimum pH, temperature, initial concentration and contact time. Although commercial activated carbon is widely used in wastewater treatment applications, it has high costs. The use of agricultural by-products as adsorbent material to purify heavy metal contaminated water has become increasingly popular through the past decade because they are less expensive, biodegradable, abundant and efficient. Instead of activated carbon, this study was focused on the inexpensive materials such as agricultural and forest waste. It was shown that these alternative adsorbents had sufficient binding capacity to remove Pb 2? ions from wastewater.

“…Basso et al, (2002) who reported that there was a correlation between lignin content of several lignocelluloses and their ability to remove heavy metals from aqueous solutions, therefore the high content of cellulose and lignin observed in the tested peanut hulls favour biosorption of metal ions. Moreover, lignocellulosic materials are very porous, have a very high specific surface area and affinity for water (Pehlivan et al, 2008), which improve the performance of these materials as sorbents. Cellulosic surface becomes partially negatively charged when immersed in water so that possesses columbic interaction with cationic species, which contributes to the high binding abilities of these materials, especially divalent metal cations (Laszlo and Dintzis, 1994).…”

The present study was conducted to evaluate the possibility of using peanut hulls for the removal of Fe +3 and Cu +2 from aqueous solutions.This paper incorporates the effects of dose, concentration and pH.Adsorption of heavy metal on adsorbents was found to increase on decreasing initial concentration, the sorption capacity strongly increased with pH in the range 3-4. The results showed that the removal of heavy metals, such as Fe +3 and Cu +2 from aqueous solution was efficient using peanut hulls as bioadsorbent. The adsorption percentage of Fe +3 and Cu +2 ions by peanut hulls were very high. The Langmuir isotherm model was the best to describe the experimental data. The maximum sorption capacity was found to be 79.28 and 96.58 mg/g for Fe +3 and Cu +2 , respectively. Over all, the present findings suggest that peanut hulls are friendly environmental bioadsorbent, efficient and low cost biosorbent which represents an excellent potential for Fe +3 and Cu +2 removals from aqueous solutions.
