Adsorption studies for the removal of nitrate using chitosan/PEG and chitosan/PVA polymer composites

Recovery of Lignocellulosic Waste from Date Palm in Activated Carbon

“…On the other hand, the adsorbed nitrates quantities by the active carbons of fibrillum and spathes of 87.84 and 87.72 (mg/g), respectively, approach that reported on another chitosan adsorbent material: Fe3O 4 /ZrO 2 /chitosan, of the order of 89.3 mg/g [31]. …”

“…Under the same operating conditions, studies [31] and [32] reported adsorbed nitrates quantities with adsorbent materials: functionalized chitosan beads and chitosan hydrogel beads of the order of 90 mg/g and 92.1 mg/g respectively, which approximates the amounts adsorbed by the active carbon of the floral handles and petioles of the order of 95.8 mg/g and 94.68 mg/g.…”

Adsorption of Nitrate onto ZnCl2‐Modified Coconut Granular Activated Carbon: Kinetics, Characteristics, and Adsorption Dynamics

“…e nitrate adsorption capacity of modified adsorbents was much higher than that of raw adsorbents. e maximum adsorption capacity obtained for ZnCl 2 -modified CGAC was higher than the corresponding values assumed by others for polyethylene glycol/chitosan and polyvinyl alcohol/chitosan (11.44 mgN·g −1 and 7.91 mgN·g −1 ) [21]. In addition, the constant 1/n in the range of 0-1 showed the favorable conditions for adsorption [38].…”

Synthesis and Impregnation of Copper Oxide Nanoparticles on Activated Carbon through Green Synthesis for Water Pollutant Removal

“…It is usually found in literature studies with materials that remove one or two of these contaminants 22,[38][39][40][41] . However, considering that it is common to find several contamination forms in drinking water and not just one, studying a material with multi-pollutant removal potential is extremely valuable, since it could make the water treatment process simpler and more cost-effective [42][43][44] .…”
