Water pollution because of inorganic contaminants is a serious problem due to the acute toxicities and carcinogenic nature of pollutants. Recently, much attention has been focused on using natural and low-cost adsorbents, especially food residues, for removing toxic metal ions. Batch removal of nickel (Ni(II)), lead (Pb(II)), and cadmium (Cd(II)) from aqueous solution using a natural adsorbent is described in this study. Effects of various parameters on adsorption capacities such as pH, adsorbent dose, and stirring time were investigated by batch experiments. The maximum adsorption capacities for Ni(II), Pb(II), and Cd(II) ions were 1.6 mg g(-1), 125 mg g(-1), and 84 mg g(-1), respectively. Characterization of the surface modification was performed with FTIR measurements. FTIR spectra showed that chemisorption takes place at the surface of the adsorbent. The Freundlich and Langmuir adsorption isotherms were used to evaluate the equilibrium data. The characteristic parameters for each isotherm were determined. The Langmuir and Freundlich isotherm provided the best correlation for Ni(II), Cd(II), and Pb(II) using banana peel.

In this study, samples of clay, tea waste, astragalus plant, chestnut shell, and egg shell were used as low-cost and eco-friendly adsorbents for the adsorption of Ni(ID from aqueous solutions. The effect of various parameters such as pH, contact time, adsorbent dose, and final volume on the adsorption capacities of these natural adsorbents were investigated by batch experiments. The adsorption capacity for Ni(II) was found to be 19.4 mg g(-1), 5.4 mg g(-1) 1.3 mg g(-1), 5.6 mg g(-1), 72.0 mg g(-1) for clay, tea waste, astragalus plant, chestnut shell, and egg shell, respectively. Egg shell has maximum adsorption capacity at pH 12, 45-minute contact time, and 0.5 g adsorbent mass. Nickel-free and nickel-loaded adsorbents were characterized by FTIR spectroscopy, which evidenced the functional groups involved in nickel uptake. This work investigated the utilization of eco-friendly and low-cost adsorbents as an alternative natural adsorbent for Ni(II) ions.
