摘要：

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.
