摘要

本研究采用简单的微波辐照法制备了裸FeO和疏水IL修饰的NPs。利用 XRD、FT-IR 和 FESEM 等多种表征技术分析了合成的 NPs 的性质。主要目的是研究 NPs 作为吸附剂从水溶液中去除染料和重金属的功效。为了评估影响 NPs 吸附效率的因素,采用批量实验法研究了各种变量,包括染料浓度、反应介质的 pH 值、纳米粒子用量和反应时间。研究结果表明,IL 改性的 NPs 比未改性的 NPs 更有效地去除 CV 染料。为了深入了解 NPs 的吸附性能,研究人员详细阐述了各种吸附等温线以及动力学研究,包括 Langmuir、Freundlich、Temkin 和伪二阶等。研究结果表明,改性 NPs 具有作为吸附剂高效去除水溶液中 CV 染料和铬的潜力。关键词NPs 离子液体 吸附 CV 染料 铬

Hydrophobic ionic liquid (IL)-based magnetic adsorbents: the way forward to remediate water pollution

In this investigation, bare and hydrophobic IL-modified FeO nanoparticles (NPs) have been synthesized using microwave irradiation. Multiple characterization techniques, including XRD, FT-IR, and FESEM, were utilized to analyze the properties of the synthesized NPs. The primary objective was to examine the efficacy of NPs as adsorbents for removing dyes and heavy metals from aqueous solutions. To evaluate the factors affecting the adsorption efficiency of the NPs, various variables including dye concentration, pH of the reaction medium, nanoparticle dosage, and reaction time were studied using the batch experiment method. The study demonstrated that the IL-modified NPs were more effective in removing CV and Cr(VI) dyes than unmodified NPs. Various adsorption isotherm intra-particle diffusion models, including Langmuir, Freundlich, and Tempkin, were elaborated to obtain insight into the adsorption behavior of the NPs. This study effectively synthesized bare and IL-modified NPs using a microwave irradiation method. The modified NPs showed promising potential as adsorbents for efficiently removing CV dye and Cr(VI) from aqueous solutions.
