In this study, Coconut Coir Pith was used to prepare a low cost bio adsorbent through chemical modification. The effect of adsorbent dosage, contact time, initial metal-ion concentration, pH and temperature on the adsorption of nickel onto chemically modified coconut coir pith was investigated. The maximum removal was observed at pH 6.0 and adsorbent dose 2.0 g/L for initial metal-ions concentration 50 mg/L. Study of temperature effect proved that the process is endothermic. Langmuir and Freundlich isotherm models were used for equilibrium adsorption data. Langmuir isotherm proved to be a better fit. Pseudo first order and pseudo second order kinetic models were applied to analyze the kinetic mechanism of adsorption. The values of Gibbs free energy ΔG°, Enthalpy ΔH° and Entropy ΔS° was calculated by the thermodynamic studies.

“…The X-ray spectra of bagasse fly-ash showed the presence of different minerals such as kaolinite, mullite, goethite, α-quartz, γ -alumina, and hematite and the scanning electron microscope (SEM) studies indicated flocs and porous nature of the material. 224 Red mud which is an abundantly available bauxite industry waste is highly alkaline in nature and is principally composed of fine particles of SiO 2 , Al 2 O 3 , Fe 2 O 3 , and TiO 2 and these have been found to be responsible for its high surface reactivity. 225 The surface electrical properties have been found to be dependent on these metal oxides.…”

A vast array of industrial waste products, agricultural by-products, and biological materials, such as bacteria, algae, yeasts, and fungi have received increased attention for heavy metal removal and recovery due to their good performance, low cost, and availability in large quantities. Such materials are cheaper, more effective alternatives to commercial activated carbon (AC) for the removal of heavy metals from aqueous solution. The authors review in greater detail the various factors affecting the adsorption capacity and cost efficiency based on the literatures and present research results. Special emphasis has been made on nature of the precursors, their pretreatment and modification, the activation conditions of time and temperature, pH of aqueous media, and regeneration/reuse potential. The authors present some of the latest important results and give a source of up-to-date literature on the ACs prepared from various low-cost precursors from agro-industrial wastes as well as from biological materials. The evolution of adsorption has turned from an interesting alternative approach into a powerful standard technique by offering a numbers of advantages: better performance in terms of ulterior adsorption capacity, rate of adsorption, solving wastewaters pollution in a cost-effective way, and overcoming part of the solid wastes problem around the world. Various advantages and challenges have been identified and a widespread and great progress in this area can be expected in the future.

Natural kaolinite obtained from Share, Nigeria was treated with ammonium carbonate to enhance the adsorption capacity. The optimum operating conditions for the adsorption of metal ions on the natural clay (SK clay) were employed on the ammonium carbonate-treated clay (SK-AC clay). The adsorption data were analysed using adsorption isotherm and kinetic models. The statistical p-values were less than 0.05, indicating that the model terms are significant for the adsorption of the metal ions. The pseudo-second-order kinetic model best describes the metal ions adsorption mechanism. The activation energy values less than 40 kJ mol-1 obtained indicated physisorption. Langmuir adsorption isotherm model fitted the adsorption data for Fe2+, Zn2+ and Cr6+ ions while the Freundlich model fitted Pb2+ ions adsorption. Analysis of thermodynamic parameters shows the adsorption is spontaneous and endothermic. The ammonium carbonate-modified clay exhibited an increase in adsorption capacity from 10.74 to 13.60 mg g-1, 16.48 to 17.38 mg g-1 and 11. 96 to 13.8 mg g-1 for Fe2+, Pb2+ and Zn2+ ions while uptake of Cr6+ decreased from 8.75 to 7.25 mg g-1. The results showed that the adsorption of Fe2+, Pb2+ and Zn2+ ions onto kaolin-containing cowlesite can be enhanced by treating it with ammonium carbonate.
