摘要

铜等重金属不仅是空气污染的问题:它们具有生物持久性,会破坏生态系统,损害土壤、地表水、森林和农作物,并在食物链中积累。我们的目标是提出量化和净化含铜废水的有效方法。本研究利用粘土处理含铜(II)废水,并采用差分脉冲阳极剥离伏安法监测 Cu2+ 的浓度。物理表征显示了粘土的多孔性。此外,粘土对 Cu2+ 的吸附动力学研究采用了伪二阶动力学模型,合适的等温线是平衡时间为 20 分钟的 Langmuir 等温线。在 pH = 6 时,Cu2+ 的吸附量最大。最大单层吸附容量为 66.54 毫克/克。

Copper Adsorption by a Clay from Central Ivory Coast: Analysis by Differential Pulse Anodic Stripping Voltammetry
Heavy metals such as copper are not only a problem for air pollution: they are bio persistent, disrupt ecosystems, damage soils, surface waters, forests, and crops, and accumulate in the food chain. The aim was to propose effective methods for quantifying and decontaminating wastewater containing copper. In this study, the treatment of copper(II)-containing wastewater was carried out using clay, and the concentration of Cu2+ was monitored using the differential pulse anodic stripping voltammetry method. Physical characterization revealed the porous nature of our clay. Furthermore, the kinetic study of Cu2+ adsorption on clay is adapted to the pseudo-order 2 kinetic model, and the appropriate isotherm is that of Langmuir with an equilibrium time of 20 min. Cu2+ adsorption is maximal at pH = 6. The maximum monolayer adsorption capacity was found to be 66.54 mg/g.
