“…Table 3 shows that the R L value is between 0 and 1, which indicates that the adsorption is favorable for pollutants studied onto the synthesized nanocomposites. A comparison between various adsorbents (cited in the literature) and prepared nanocomposites (in this study) was done for the removal of AB 1 and Cr(VI) ions (Table 4) [39,[70][71][72][73][74][75][76][77][78][79][80][81][82][83][84]. As seen from the Table 4, the prepared adsorbent is more effective than the other reported ones.…”

In this study, magnetic nanocomposites viz. SiO 2 @CoFe 2 O 4 nanoparticles decorated on graphene oxide were synthesized using solvothermal and sol-gel processes. The prepared nanocomposite materials were used as magnetic adsorbents for the removal of organic and inorganic pollutants (acid black 1 dye and Cr(VI) ions as model pollutants) from aqueous solution. The structure, morphology and other physico-chemical properties of nanocomposites were characterized by X-ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM), high resolutiontransmission electron microscopy (HR-TEM), vibrating sample magnetometer (VSM), X-ray Photo spectroscopy (XPS), zeta potential and Fourier infrared (FT-IR) spectroscopy. Batch mode adsorption studies were conducted with the prepared nanocomposites to determine the maximum adsorption capacity of acid black 1 dye and Cr(VI) ions as a function of contact time, pH, adsorbent dosage and initial adsorbate concentrations. Different kinetic and isotherm models were tested to describe and elucidate the adsorption mechanisms. Based on the experimental results obtained, the synthesized materials proved to exhibit considerable potential for the removal of acid black 1 and Cr(VI) ions from aqueous solution.

Ionic liquids (ILs) have emerged as a novel class of chemical compounds for the development of advanced (multi)functional materials with outstanding potential in applications of several areas due to their unique properties and functionalities. The combination of ILs with polymers, in a composite, allows for developing smart materials, which synergistically combine the features of specific polymers and ILs. Moreover, ILs can be extensively modified by the incorporation of functional groups with specific properties into the cation, anion, or both. Thus, it is possible to tune the IL, the polymer, or both to obtain a broad spectrum of multifunctional composites and address the specific requirements of many applications. This work focusses on advanced materials and strategies concerning ILs and polymers for the development of smart IL/polymer‐based materials for applications including responsive and sensitive sensors, actuators, environment, batteries, fuel cells, and biomedical applications.

In this work, the 2-AMPR resin was used to separate rhenium from uranium in acidic aqueous solution. The morphology and structure of 2-AMPR before and after adsorption were characterized using SEM, FT-IR, and XPS. In both the static and dynamic adsorption-desorption experiments, the 2-AMPR resin showed excellent enrichment capacity for rhenium, which means that the 2-AMPR anion exchange resin has good industrial application prospects in terms of recovery of rhenium.
