“…A broad stretch between 3000 and 3500 cm −1 was also observed, which may be attributed to a combination of amines (N−H stretch), hydroxyls from the Al 2 O 3 support, or adsorbed atmospheric H 2 O (O−H stretch). [ 35,36 ] PEI/Al 2 O 3 under dry DAC conditions had a CO 2 adsorption capacity of 1.43 mmol g −1 , similar to studies on MOF‐ [ 37 ] and silica‐ [ 38 ] supported PEI under similar conditions. This capacity, when normalized by the sample's nitrogen content, corresponds to an amine efficiency (A.E.)…”

“…Also, the adsorption capacity of 3D_W/M at pH 6.4, was higher than that of the materials zinc oxide nanocrystal-decorated regenerated micro-fibrillated cellulose scaffolds (from jute) [56], for removal of As(V) with adsorption capacity of 4.421 mg g -1 . Interestingly, three materials, adsorbents NC-MA/ L-MG [54], Magnetite [54] and PEI-Al 2 O 3 [53], on the pH pzc similar to 3D_W/M, showed the higher adsorption capacity 85.3 mg g -1 , 91.2 mg g -1 and 61.3 mg g -1 , respectively, than in the material 3D_W/M, whileMC-O/NC-L-MG [54] showed the lower value of the adsorption capacity, 18.5 mg g -1 . As(V) Dust Ferric Hydroxide (DFH) 5.3 6.9 mg g -1 (pH 7.9) [55] As(V)…”

“…With the growing demand for high-performance and high-stability adsorbent materials, ceramic balls, as adsorbents for various gases and liquids, have achieved good results in environmental protection, such as sewage treatment, waste gas treatment, and air purification. However, in terms of high selectivity, ceramic balls also need to be modified to achieve better performance [27][28][29]. Therefore, it is of great significance to load polymer materials on ceramic balls.…”
