Abstract

The MIL-100(Fe) was employed for the remediation of toluene-contaminated water. The MIL-100(Fe) samples synthesised for this work exhibit high thermal (300 °C) and chemical (pH range 2–10) stability. Adsorption kinetics and isotherms were fitted to the Elovich and Temkin models. The pH of the aqueous sample containing Toluene impacted the adsorption capacity of MIL-100(Fe) through modulation of the MOF ζ potential. As a result, we concluded that MIL-100(Fe) is most effective at adsorbing toluene in the 6–10 pH range, a finding that underscores its potential in water treatment. The maximum Langmuir adsorption capacity of 318.48 mg g⁻¹ was determined. MIL-100(Fe) showed excellent adsorption–desorption performance and stability; hence, it can be used repeatedly without losing toluene adsorption capacity. FT-IR spectra suggest that π–π interactions serve a crucial role during toluene adsorption, further confirming the effectiveness of MIL-100 (Fe) in water treatment.

使用 MIL-100(Fe)高效去除水溶液中的甲苯

MIL-100(Fe) 被用于甲苯污染水的修复。为这项工作合成的 MIL-100(Fe)样品具有很高的热稳定性（300°C）和化学稳定性（pH 值范围 2-10）。吸附动力学和等温线均符合 Elovich 和 Temkin 模型。通过调节 MOF ζ 电位，发现含甲苯水样的 pH 值会影响 MIL-100(Fe)的吸附能力。因此，我们得出结论，MIL-100(Fe) 在 pH 值为 6-10 的范围内对甲苯的吸附效果最好，这一发现突出了它在水处理方面的潜力。测定的最大朗缪尔吸附容量为 318.48 mg g-1。MIL-100(Fe) 具有出色的吸附-解吸性能和稳定性，因此可反复使用而不会损失甲苯吸附能力。傅立叶变换红外光谱表明，π-π 相互作用在甲苯吸附过程中起着关键作用，这进一步证实了 MIL-100 (Fe) 在水处理方面的有效性。
