“…In addition, a slight increase in the % atomic percentage of C after adsorption demonstrated that it both maintained good stability during adsorption and combined with C from the structure of RR120 [26]. Finally, the observation of S element, after the adsorption process, confirmed the adsorption of RR120 dye molecules on the surface of the nanocomposite [30].…”

A graphene oxide/zirconium oxide (GO/ZrO2) nanocomposite was developed and evaluated for the efficient removal of Reactive Red120 (RR120) dye. The characterization of the GO/ZrO2 nanocomposite was carried out by Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), Raman spectroscopy, Brunauer‐Emmett‐Teller (BET), field emission scanning electron microscopy (FESEM), and energy dispersive X‐ray (EDX) spectroscopy. Box‐Behnken design (BBD) was used as a statistical optimization to evaluate the effects of adsorption parameters, including adsorbent concentration, RR120 amount, and removal time. The study describes the GO/ZrO2 nanocomposite adsorbent, which has a potential application in the treatment of anionic dye‐contaminated water.

“…Loading substances rich in hydroxyl groups onto porous materials can further enhance their dye adsorption performance. Mohammed et al [57] dissolved chitosan (CHT) in acetic acid and adjusted the pH value to form CHT microspheres. The CHT microsphere solution and coal fly ash (CFA) were added to the epichlorohydrin (ECH) solution to produce a biocomposite adsorbent of covalently crosslinked chitosan-epichlorohydrin/coal fly ash (CHT-ECH/CFA 50 ).…”

The discharge and accumulation of coal-based solid waste have caused great harm to the ecological environment recently. Coal-based solid wastes, such as coal gangue and fly ash, are rich in valuable components, such as rare earth elements (REY), silicon dioxide, alkali metal oxides, and transition metal oxides, which can be used to synthesize various functional Si-based porous materials. This article systematically summarizes the physicochemical characteristics and general processing methods of coal gangue and fly ash and reviews the progress in the application of porous materials prepared from these two solid wastes in the fields of energy and environmental protection, including the following: the adsorption treatment of heavy metal ions, ionic dyes, and organic pollutants in wastewater; the adsorption treatment of CO2, SO2, NOx, and volatile organic compounds in waste gas; the energy regeneration of existing resources, such as waste plastics, biomass, H2, and CO; and the preparation of Li–Si batteries. Combining the composition, structure, and action mechanism of various solid-waste-based porous materials, this article points out their strengths and weaknesses in the above applications. Furthermore, ideas for improvements in the applications, performance improvement methods, and energy consumption reduction processes of typical solid-waste-based porous materials are presented in this article. These works will deepen our understanding of the application of solid-waste-based porous materials in wastewater treatment, waste gas treatment, energy regeneration, and other aspects, as well as providing assistance for the integration of new technologies into solid-waste-based porous material preparation industries, and providing new ideas for reducing and reusing typical Chinese solid waste resources.

“…Figure 1b shows the XRD data used to verify the crystalline structure of the composite material. The XRD pattern shows a huge hump around 2θ = 21.22, which is a chitosanspecific peak [20]. Furthermore, the sharp peaks at 30.11, 35.49, 43.21 are mostly composed of crystalline phases, such as quartz, hematite, and alumina, which are all formed from zeolite-and zirconium-based materials.…”

“…However, because of its low tensile strength and dissolution under acidic conditions, the use of chitosan directly in wastewater treatment technologies is not recommended. Therefore, chitosan must be modified to increase its chemical stability and adsorption capability [20]. The selection of an appropriate modification method and modifying agent is crucial for assessing the quality and functionality of the product created during the modification process.…”

Phosphate (PO43−) is an essential nutrient in agriculture; however, it is hazardous to the environment if discharged in excess as in wastewater discharge and runoff from agriculture. Moreover, the stability of chitosan under acidic conditions remains a concern. To address these problems, CS-ZL/ZrO/Fe3O4 was synthesized using a crosslinking method as a novel adsorbent for the removal of phosphate (PO43−) from water and to increase the stability of chitosan. The response surface methodology (RSM) with a Box–Behnken design (BBD)-based analysis of variance (ANOVA) was implemented. The ANOVA results clearly showed that the adsorption of PO43− onto CS-ZL/ZrO/Fe3O4 was significant (p ≤ 0.05), with good mechanical stability. pH, dosage, and time were the three most important factors for the removal of PO43−. Freundlich isotherm and pseudo-second-order kinetic models generated the best equivalents for PO43− adsorption. The presence of coexisting ions for PO43− removal was also studied. The results indicated no significant effect on PO43− removal (p ≤ 0.05). After adsorption, PO43− was easily released by 1 M NaOH, reaching 95.77% and exhibiting a good capability over three cycles. Thus, this concept is effective for increasing the stability of chitosan and is an alternative adsorbent for the removal of PO43− from water.
