In this paper, the adsorption behavior of Pb 2+ ions from aqueous solutions onto castor stem as a natural adsorbent was investigated under various experimental conditions. Characterization of castor sorbent was evaluated by SEM, XRD, FTIR, TGA, BET surface area analysis, and CHNS elemental analyses. Operational parameters such as pH, contact time, initial ion concentrations, sorbent amount, particle size, competing ions, and temperature were also studied. Adsorption data fitted well with the Langmuir and Freundlich models. However, Freundlich isotherm displayed a better fitting model than Langmuir isotherm because of the higher correlation coefficient that the former exhibited, thus, indicating the applicability of multilayer coverage of the Pb (II) on the surface of adsorbent. On the basis of distribution studies, the distribution coefficient (K d ) increases with increasing the reaction temperature of the solution. Thermodynamic parameters, ∆H o , ∆G o , and ∆S o were calculated and indicated an endothermic and spontaneous process.

The widespread use of heavy metals in different manufacturing processes has resulted in their presence in the air, soil and aquatic ecosystems. Many manufacturing processes release their effluents into nearby streams and rivers due to non-availability of waste treatment technologies in the developing world. Industrialization has therefore been reported to be a major anthropogenic source of these elements and their compounds waterbodies. Conventional methods that are currently being used in the developed world (such as chemical precipitation, ultra-filtration, reverse osmosis, etc) are expensive and so, unaffordable to small-scale businesses prevalent in developing economies. The need for alternative, cheaper and available technologies therefore, cannot be over-emphasized. This study attempted to remove heavy metals (Cu 2+ and Cd 2+ ) from simulated and industrial (paint and textile) wastewaters using sugarcane biomass. A synthetic resin (Chelex) was used as control. Batch sorption experiments were conducted to assess the influence of contact time, adsorbent dose, adsorbate concentration, pH, agitation speed, temperature and particle size. Increases in the parameters (except particle size) gave corresponding increases in percentage adsorption of both metals. Optimal temperature for adsorption was achieved at 50 o C above which adsorption declined considerably. Experimental data for Cu 2+ and Cd 2+ fitted well into freundlich and langmuir isotherms. In textile effluent, 100% adsorption was achieved for both metals using sugarcane biomass in contrast to 89% and 91% for Cu 2+ and Cd 2+ respectively in chelex, a synthetic resin. Similarly, adsorption was 100% for both metals using the biosorbent. Sugarcane biomass may therefore be utilized for water and wastewater remediation in the developing world. Its biodegradability gives comparative advantage over alternative synthetic and expensive resins since its disposal will be more environmentally friendly.

“…From both the environmental and the economical points of view, this technique has significant advantages including high efficiency in removing very low levels of heavy metals from dilute solutions, easy handling, high selectivity, lower operating cost, minimum production of chemical or biological sludge and regeneration of adsorbent. Some of the biosorbents used for removal of Cu (II) are rice husk (Wong et al, 2003) coffee husk (Oliveira et al, 2008), crab shell (Cochrane et al, 2006), fern (Ho et al, 2002), BGB , sunflower (Sun and Shi, 1998), chemically modified rice husk (Jaman et al, 2009), protonated rubber leaf powder (Hanafiah and Ngah, 2009), walnut, hazelnut and almond-shells (Altun and Pehlivan, 2007), cotton boll (Ozsoy and Kumbur, 2006), Pinus sylvestris L. (Ucun et al, 2009), sour orange residue (Khormaei et al, 2007).…”

This study focused on the effect of various experimental parameters like adsorption kinetics, effects of pH, temperature, initial Cu(II), biosorbent dose and agitator speed on biosorption of Cu (II) from aqueous solution onto Catla catla fish scales. Analysis of Fourier-transform infrared (FTIR) spectrum, scanning electron microscopy (SEM) images and energy-dispersive X-ray (EDX) spectroscopy suggested that both organic functional groups and inorganic constituent take part in the Cu (II) uptake process. Both the linear and nonlinear forms of the Langmuir and Freundlich adsorption isotherm models (at low concentration) predicted the equilibrium adsorption isotherm data fairly well. The maximum Cu (II) adsorption capacity of fish scale was determined to be 79.35 mg/g at 40°C and pH 5.5 by nonlinear regression. A mathematical model developed assuming the adsorption process to be diffusion controlled gave satisfactory fit to the experimental batch kinetic data.
