Fabrication of a novel chitosan Schiff bases hydrogel derivatives for the removal of anionic dyes from wastewater
RE Khalifa, S Aboulhadeed, HM Ahmed… - Desalination and Water …, 2021 - Elsevier
In this research, eco-friendly chitosan Schiff base hydrogel derivatives, as new adsorbents
for anionic dye, Methyl orange (MO), were synthesized via coupling with 4-dimethylamino
benzaldehyde (chitosan Schiff base (I)) and benzophenone (chitosan Schiff base (II)). The
adsorbents' structure was examined and characterized by Fourier-transform infrared
spectroscopy, scanning electron microscopy, thermogravimetric analysis, and differential
scanning calorimetry. The MO adsorption percentage of the developed chitosan Schiff bases …
