Abstract Increasing world population, urbanization, and industrialization have led to an increase in demand production consumption, resulting industrial solid wastes pollutant levels water. These two main consequences become global problems. The high Si Al content of suggests that they can be used as raw materials for the synthesis zeolites. In this context, when literature studies conducted obtain synthetic zeolites are evaluated, it is seen hydrothermal method generally used. order improve performance terms energy cost, time, even product quality, additional methods such alkaline fusion, ultrasonic effect, microwave support been developed. synthesized by different techniques exhibit superior properties surface area well-defined pore sizes, thermal stability, cation exchange capacity, regeneration ability, catalytic activity. Due these specific properties, recognized one most effective removal pollutants. toxic heavy metals dyes water their carcinogenic effects long-term exposure pose a serious risk living organisms. Therefore, should treated at specified before discharge environment. review study, processes including developed from were evaluated. Studies using health environmental risks reviewed. addition, EPMA, SEM, EDX, FTIR, BET, AFM, 29 27 NMR techniques, which characterization zeolites, presented thermodynamics adsorption, effect temperature, pH investigated. It expected consumption reduced large-scale applications alternative zeolite introduction into industry. envisaged utilizing will obtaining green technology. use wide variety applications, especially problems, holds great promise.

Physicochemical synergistic adsorption of CO₂ by PEI‐impregnated hierarchical porous polymers

Greenhouse Gases Science and Technology, Journal Year: 2024, Volume and Issue: 14(2), P. 270 - 283

Published: Feb. 13, 2024

Abstract Amine‐functionalized porous polymers have been considered as a prominent chemical adsorption material for carbon capture and storage (CCS) process, because of their large capacity high selectivity. By comparison, the low energy‐consumption desorption recyclability are advantages physical approach. In this work, an amine‐functionalized hierarchical polymer was prepared by HIPE (high internal phase emulsions) template amine impregnation strategy, applied CO 2 adsorbent to realize simultaneously. First, matrix poly(styrene‐glycidyl methacrylate) method. The formed meso/micropores in typical could attract molecules, where achieved. Subsequently, PEI (polyethyleneimine) impregnated into with abundant macropores, numerous amino groups provided reaction sites, As result, effective obtained via controlling structure changing volume fraction dispersive phase, condition loading. Aided groups, reached 3.029 mmol/g. Moreover, thermodynamics confirmed physicochemical synergistic adsorption, then Q st reduced 31–42 kJ/mol good cyclic stability obtained. conclusion, showed industrial application prospect. © 2024 Society Chemical Industry John Wiley & Sons, Ltd.
