摘要

本研究考察了水溶液中的镍(II)金属离子在海草物理活性吸附剂(AC-PO)上的吸附能力。研究考察了 pH 值、吸附剂用量、镍离子浓度、温度和接触时间等参数对 AC-PO 吸附镍(II)离子的影响。动力学数据与假二阶模型十分吻合。Ni(II) 离子的吸附符合 Langmuir、Freundlich 和 D-R 等温线。Langmuir 模型较好地反映了数据(0.9993)。计算了 Ni(II)离子的热力学参数,如 ∆G°、∆H° 和 ∆S°,并确定吸附是自发的、内热的。通过能量色散光谱(EDS)进行定性化学分析发现,AC-PO 吸附剂在吸附镍离子时存在离子交换。根据本研究得出的结果,可以说 AC-PO 吸附剂在去除水溶液中的镍(II)离子方面具有相当高的吸附能力。

Adsorption properties of Ni(II) ions from an aqueous solution onto activated carbon prepared from Posidonia oceanica seagrass

This study examined the adsorption ability of Ni(II) metal ions from aqueous solutions on a physically activated adsorbent of Posidonia oceanica seagrass (AC-PO), which is both economically and naturally available. The effects of pH, amount of adsorbent, concentration of nickel ions, temperature, and contact time, which are among the parameters affecting the adsorption of Ni(II) ions on AC-PO, were examined. The kinetic data fit well with the pseudo-second-order model. The adsorption of Ni(II) ions showed compliance with Langmuir, Freundlich, and D-R isotherms. The Langmuir model showed better representation of data (0.9993). The maximum adsorption capacity of AC-PO for nickel ions was 138.89 mg·g−1.at 25 °C The thermodynamic parameters such as ∆G°, ∆H°, and ∆S° were calculated for the Ni(II) ion, and it was determined that the adsorption was spontaneous and endothermic. In qualitative chemical analysis by energy dispersive spectroscopy (EDS), it was found that there was ion exchange with adsorption of nickel ions on the AC-PO adsorbent. According to the results obtained from this study, it can be said that the adsorption ability of the AC-PO adsorbent is quite high in the removal of Ni(II) ions from aqueous solutions.
