“…Their results also suggested that hybrid functionalization is more useful to produce CO2 adsorbents from PE-MCM-41 with higher performance than their grafted or impregnated counterparts. The synergistic effect of other N-containing materials, including ionic liquids to promote the adsorption capacity of MCM-41, were also studied [54,72,73].…”

Over the past decade, amine-loaded solid adsorbents for capturing CO2 from power plants have been widely studied. Various nitrogen (N) sources have been used for this purpose, and the current range of adsorbents, referred to here as N-functionalized solid adsorbent (NFSAs), are the subject of this review. The main synthesis methods of NFSAs are described and recent progress in the field discussed. Criteria for improving NFSA performance are highlighted with reference to a variety of solid supports, providing guidance on the selection of highly efficient, inexpensive adsorbents. A thorough assessment of adsorption mechanisms and factors influencing the adsorption process is given. The review concludes by exploring future research and development opportunities, as well as pathways for commercializing NFSAs.

“…The synthesis scheme was based on a simple one‐step reaction, which allowed it to be scalable for the further development of industrial CO 2 capture and storage units. Moreover, compared with un‐functionalized mesoporous substrates, aminated PVC adsorbent was found to have exceptional hydrophobic characteristics which enable it to be used in elevated moisture content flue gases …”

“…Moreover, compared with un-functionalized mesoporous substrates, aminated PVC adsorbent was found to have exceptional hydrophobic characteristics which enable it to be used in elevated moisture content flue gases. 87 In Europe, recovery of 69.2% of post-consumer plastics was accomplished via energy recovery processes and recycling, whereas the disposal of the rest, 30.8%, took place together with the municipal solid wastes in landfills which in return reduced the landfill capacity as a result of low solid waste density, in 2014. 88 Fu et al reported a technique for the synthesis of hyper crosslinked polymers using Friedel-Crafts reaction employing waste-expanded polystyrene foam as raw material and 1,2-dichloroethane as both solvent and crosslinker.…”

The mass production of polymer products, in particular plastics, and their widespread use depending on the inherent advantages they have, make these materials ironically a threat to life on Earth. Polymer recycling is being considered as one of the most widely accepted remedies to the threat of growing amounts of plastic waste by both the public and scientists. In practice, recycling is associated with many difficulties, such as problems related to separation, sorting and cleaning operations, lack of fiscal subsidies, instability of selective garbage separation programs, high transport and electricity costs, etc. Still, a large section of society and the authorities agree on the necessity and importance of recycling to protect the environment, and natural habitats and resources for future generations in a balanced manner to conserve raw materials, and to reduce energy consumption, municipal solid waste production and greenhouse gas emission. The recycling effort is almost endless in itself and includes a variety of approaches such as refurbishing, mechanically reshaping, chemically treating, thermally utilizing, etc. Some novel approaches such as application in carbon capture or synthesis of carbon nanostructures from the plastic waste are among the new process technologies of recycling. From traditional and promising polymer waste utilization approaches, this review will highlight sustainable methods to reduce impacts of plastic waste on the environment. © 2018 Society of Chemical Industry

“…Establishing a sustainable approach to the recycling of waste PVC is of great interest to the environmental communities. For example, a convenient route has been developed to bond amines and alkyl chloride groups by nucleophilic substitution reactions through secondary chlorine groups in the PVC backbone [ 18 ]. Polyethylenimine (PEI) is an amine-rich water-soluble polymer that is widely used for surface modification [ 19 ].…”

In this study, the optimal conditions for the fabrication of polyethylenimine/polyvinyl chloride cross-linked fiber (PEI/PVC-CF) were determined by comparing the adsorption capacity of synthesized PEI/PVC-CFs for Reactive Yellow 2 (RY2). The PEI/PVC-CF prepared through the optimal conditions was characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and Brunauer–Emmett–Teller (BET) analyses. Several batch adsorption and desorption experiments were carried out to evaluate the sorption performance and reusability of PEI/PVC-CF for RY2. As a result, the adsorption of RY2 by PEI/PVC-CF was most effective at pH 2.0. A pseudo-second-order model fit better with the kinetics adsorption data. The adsorption isotherm process was described well by the Langmuir model, and the maximum dye uptake was predicted to be 820.6 mg/g at pH 2.0 and 25 °C. Thermodynamic analysis showed that the adsorption process was spontaneous and endothermic. In addition, 1.0 M NaHCO3 was an efficient eluent for the regeneration of RY2-loaded PEI/PVC-CF. Finally, the repeated adsorption–desorption experiments showed that the PEI/PVC-CF remained at high adsorption and desorption efficiencies for RY2, even in 17 cycles.
