“…Various improved and innovative methods such as reverse osmosis, precipitation, coagulation, ion exchange, solvent extraction, adsorption, membrane filtration, ultra-filtration and photoreduction have been developed to remove metal pollutants from contaminated water and wastewater (Bailey et al 1999;Barron-Zambrano et al 2002;Chen and Wang 2000;Hunsom et al 2005;Kentish and Stevens 2001;Pacheco et al 2006). Among the above-mentioned processes, adsorption plays a pivotal role in removing metals from the aqueous phase using various biomaterial sorbents, algae (Holan et al 1993), fungi, sugar cane bagasse (Cerino Córdova et al 2011;Peterlene et al 1999), rice husk, wheat barn (Nouri et al 2007), pine bark, olive cake (Doyurum and Celik 2006), coconut husk, chitin (Benguella and Benaissa 2002), ash, activated carbon (Jusoh et al 2007;Onundi et al 2011;Zavvar Mousavi and Seyedi 2011), etc. Clays, zeolite, calcite, manganese nodule residue (Agrawal and Sahu 2006;Tashauoei et al 2010), perlite (Hasan et al 2006) and peat (Gabaldon et al 2006) have also been employed to remove metals from the water phase.…”

The present study attempted to identify the efficient hazardous metal-removing sorbent from specific types of soil, upper and middle layer shirasu, shell fossil, tuff, akadama and kanuma soils of Japan by physicochemical and metal (arsenic, cadmium and lead) removal characterizations. The physico-chemical characteristics of soil were evaluated using X-ray diffraction and scanning electron microscopy with energy dispersive spectroscopy techniques, whereas metal removal properties of soil were characterized by analyzing removal capacity and sorption kinetics of potential metal-removing soils. The chemical characteristics revealed that all soils are prevalently constituted of silicon dioxide (21.83-78.58 %), aluminum oxide (4.13-38 %) and ferrous oxide (0.835-7.7 %), whereas calcium oxide showed the highest percentage (65.36 %) followed by silicon dioxide (21.83 %) in tuff soil. The results demonstrated that arsenic removal efficiency was higher in elevated aluminum oxide-containing akadama (0.00452 mg/L/g/h) and kanuma (0.00225 mg/L/ g/h) soils, whereas cadmium (0.00634 mg/L/g/h) and lead (0.00693 mg/L/g/h) removal efficiencies were maximum in elevated calcium oxide-containing tuff soil. Physicochemical sorption and ion exchange processes are the metal removal mechanisms. The critical appraisal of three metal removal data also clearly revealed cadmium [ lead [ arsenic order of removal efficiency in different soils, except in tuff and akadama soils followed by lead [ cadmium [ arsenic. It clearly signified that each type of soil had a specific metal adsorption affinity which was regulated by the specific chemical composition. It may be concluded that akadama would be potential arsenicremoving and tuff would be efficient cadmium and leadremoving soil sorbents.

“…Increasing the temperature is familiar to raise the rate of diffusion of the adsorbate, due to the reduction in the viscosity of the solution. Besides, changing the temperature will alter the equilibrium biosorption capacity of the immobilized bacterial cells for a specific biosorbent [42].…”

One of the main environmental concerns of today is the occurrence of arsenic in wastewater. Targeting a solution for this problem, several efforts have been made towards research and application of cost-effective and effortlessly adaptable processes. The ability of a biofilm of Bacillus arsenicus MTCC 4380 supported on sawdust/MnFe 2 O 4 composite to biosorb/ bioaccumulate As(III) and As(V) was investigated in batch experiments. Optimum biosorption/bioaccumulation conditions were determined as a function of contact time and temperature. The equilibrium was achieved after about 220 min at 30°C temperature. Nonlinear regression analysis was done to determine the best-fit kinetic model based on three correlation coefficients and three error functions and also to predict the parameters involved in kinetic models. The results showed that both Brouers-Weron-Sotolongo and Avrami models for both As(III) and As(V) were capable of providing realistic explanation of biosorption/bioaccumulation kinetic. Applicability of mechanistic models showed that the rate controlling step in the biosorption/bioaccumulation of both As(III) and As(V) was film diffusion rather than intraparticle diffusion. The estimated thermodynamic parameters ΔG 0 , ΔH 0 , and ΔS 0 revealed that biosorption/bioaccumulation of both As(III) and As(V) was feasible, spontaneous, and exothermic under examined conditions. The activation energy (E a ) estimated from Arrhenius equation specified the nature of biosorption/bioaccumulation being ion exchange type. The effect of co-existing ions such as Cu 2+ , Zn 2+ , Bi 3+ , Cd 2+ , Fe 3+ , Pb 2+ , Co 2+ , Ni 2+ , Cr 6+ , and SO 4 2− at different concentrations was inspected.

“…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.
