“…The biosorption of Pb(II) ions on the E. crassipes is therefore mostly monolayer. Similar results were obtained by Panda et al [11] and Oliveira et al [5]. The value for b (affinity for the metal ions) for adsorption of Pb(II) ions on the biomass was found to be 0.0234.…”

ABSTRACT. This paper reports the kinetic and equilibrium studies of Eichhornia crassipes root biomass as a biosorbent for Pb(II) ions from aqueous system. Batch adsorption studies were carried out to examine the influence of various parameters such as the pH, contact time, adsorbent dose, initial metal ion concentration, temperature and agitation speed on the metal ion uptake. Uptake of Pb(II) ions on the E. crassipes roots showed a pH-dependent profile. The maximum metal uptake values were 164 µg/mL. Langmuir model fitted the experimental sorption equilibrium data with a good fit (R 2 > 0.99). The biosorption kinetics was described by the pseudo-second-order model (R 2 > 0.99).

“…Most of these are agriculture wastes or by-products, which are considered to be low value products. Different types of biomass have been investigated for their capacity to remove heavy metals from aqueous solutions with a considerable degree of success [4][5][6][7][8][9][10][11].…”

“…The peak at 3,435 cm -1 after dye biosorption became broadened, indicating the involvement of an NH group in biosorption. The strong and broad band ranging from 3,600 to 3,200 cm -1 was assigned to an overlapping of the O-H and N-H stretching vibrations (Panda et al 2008;Sun et al 2009). Moreover, obvious displacements were observed at 1,639-635 cm -1 and 1,240-1,232 cm -1 , suggesting that the biosorption involved C = C stretching (-CH = CH-) and S = O stretching vibrations (Ding et al 2012;Elangovan et al 2008).…”

The kinetics and thermodynamics of the biosorption of textile dye Congo Red on anaerobic activated sulfidogenic sludge were examined. The influence of different adsorption parameters such as pH, temperature, contact time and initial dye concentrations on the biosorption capacity was also investigated. The sulfidogenic sludge showed a maximum biosorption density of 238.90 mg dye/g cell for Congo Red at an initial dye concentration of 1,000 mg/L, pH 3.5 and 22°C, which is higher than that of many other adsorbents reported in the literature. The biosorption processes obeyed the Langmuir isotherm and exhibited pseudo-second-order rate kinetics. The thermodynamic parameters indicated the spontaneous and exothermic nature of Congo Red biosorption. The Fourier transform infrared spectra revealed the dye interaction with the biomass. Scanning electron microscopy showed significant changes in the surface morphology of the sludge after dye biosorption. These results showed that sulfidogenic sludge biomass is an attractive alternative low-cost biosorbent for the removal of the dye from aqueous media.

“…The search for new technologies for the removal of toxic metals has directed attention to biosorption phenomenon which is based on the metal binding capacity of agricultural wastes (Zacaria 2002). In recent years, a number of agricultural and forestry by-products such as rice husk (Ajmal et al 2003), pine bark (Al-Asheh and Duvnjak 1998), saw dust (Bulut and Tez 2007), Araucaria heterophylla (Sarada et al, 2013), lignin (Srivastava et al 1994), cork biomass (Chubar et al 2004), Lathyrus sativus husk (Panda et al 2008), Zea mays cob powder (Goyal and Srivastava, 2009), Acacia leucocephala bark powder (Munagapati et al, 2010), Parthenium hysterophorus weed (Ajmal et al, 2006), wheat bran (Nouri et al 2007), Eleocharis acicularis (Miretzky et al, 2010), Eichhornia crassipes (Módenes et al, 2011), Grape pomace , orange peel (Feng et al, 2011) have been used for heavy metal removal from waters and wastewaters.…”

The present study attempted to analyze the biosorption behavior of novel biosorbent, Araucaria heterophylla (green plant) biomass, to remove Cd ?2 from solutions against various parameters, i.e., initial metal ion concentration, pH, temperature, sorbent dosage and biomass particle size. The maximum biosorption was found to be 90.02% at pH 5.5 and biosorption capacity (q e ) of Cd ?2 is 9.2506 mg g -1 . The Langmuir and Freundlich equilibrium adsorption isotherms were studied and it was observed that Freundlich model is the best fit than the Langmuir model with correlation co-efficient of 0.999. Kinetic studies indicated that the biosorption process of Cd ?2 well followed the pseudo-second-order model with R 2 0.999. Thermodynamic studies observed that the process is exothermic (DH°negative). Free energy change (DG°) with negative sign reflected the feasibility and spontaneous nature of the process. The chemical functional -OH groups, CH 2 stretching vibrations, C=O carbonyl group of alcohol, C=O carbonyl group of amide, P=O stretching vibrations and -CH groups were involved in the biosorption process. The XRD pattern of the A. heterophylla was found to be mostly amorphous in nature. The SEM studies showed Cd ?2 biosorption on selective grains of the biosorbent. It was concluded that A. heterophylla leaf powder can be used as an effective, low-cost, and environmentally friendly biosorbent for the removal of Cd ?2 from aqueous solution.
