“…Based on this, a pH of 6 having a removal efficiency of 86.2% is considered to be optimum for further studies. This is comparable to the result obtained by (Peternele et al [15]) on the removal of metal ions by low cost adsorbent from an aqueous solution. …”

In this particular research, microwave incinerated sugarcane bagasse ash (MISCBA) obtained by incinerating the sugarcane bagasse was utilized as a low cost adsorbent for the removal of ZnCl 2 metal ion from synthetic wastewater through the batch adsorption approach. It was realized that the thermal incineration of the sugarcane bagasse changed the morphological structure of the bagasse. In addition, the surface structure of the sugarcane bagasse has changed from non-porous to a porous surface after incineration. The effect of pH and contact time, adsorbent dosage and initial metal concentration was investigated in this study. A pH value of 6 was found to be optimum. Furthermore, the percentage of adsorption improves with an increase in contact time and a contact time of 180 mins was found to be optimum after attaining equilibrium with a removal efficiency of 96.3%. The equilibrium data was well described by Freudlich as well as the Langmuir model with a correlation coefficient of 0.997 and 0.984. The kinetic data fitted well into the pseudo-second order model.

“…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.

“…The treatment of cadmium contaminated water is similar to that of many metal contaminated effluents. There are several methods to treat the metal contaminated effluent such as precipitation, ion-exchange, adsorption etc., but the selection of the treatment method is based on the concentration of waste and the cost of treatment (Dezuane, 1990;Peternele et al, 1999;Cheung et al, 2001;Ajmal et al, 2003). In the last few years, adsorption has been shown to be an economically feasible alternative method for removing trace metal from wastewater and water supplies (Allen and Brown, 1995;Gabaldon et al, 1996;Mahvi et al, 2004).…”

-The adsorption behavior of rice husk for cadmium ions from aqueous solutions has been investigated as a function of appropriate equilibrium time, adsorbent dose, temperature, adsorbate concentrations and pH in a batch system. Studies showed that the pH of aqueous solutions affected cadmium removal with the result that removal efficiency increased with increasing solution pH. The maximum adsorption was 98.65% at solution pH 6, contact time 60 min and initial concentration of 25 mg/L. The experimental data were analysed by the Langmuir, Freundlich and Temkin models of adsorption. The characteristic parameters for each isotherm and related correlation coefficients have been determined. Δ have also been evaluated and it has been found that the sorption process was feasible, spontaneous and exothermic in nature. The kinetics of the sorption were analysed using the pseudo-first order and pseudo-second order kinetic models. Kinetic parameters, rate constants, equilibrium sorption capacities and related correlation coefficients for each kinetic model were calculated and discussed. It was shown that the adsorption of cadmium could be described by the pseudosecond order equation, suggesting that the adsorption process is presumably a chemisorption. The rice husk investigated in this study showed good potential for the removal of cadmium from aqueous solutions. The goal for this work is to develop inexpensive, highly available, effective metal ion adsorbents from natural waste as alternative to existing commercial adsorbents.
