Abstract
New modified chitosan Schiff base (3E-2H-BCs) was prepared via a condensation reaction between 3-ethoxy-2-hydroxybenzaldehyde and chitosan. The title compound 3E-2H-BCs was characterized by various techniques such as FT-IR, UV-Vis, XRD, SEM and TG-DTA. The results show that the title compound 3E-2H-BCs was successfully prepared. In addition, the title compound 3E-2H-BCs applied as an efficient adsorbent for methyl green (MG) removal from aqueous solution and the effect of contact time and adsorbent dosage has been studied. The equilibrium of dye adsorption by 3E-2H-BCs was reached at 1 min contact time at the presence of MG. The dye adsorption results show that the title compound 3E-2H-BCs is as an efficient adsorbent for other dye removal from wastewater.
