Paper Title:
Adsorption of Dyes from Wastewater onto Cross-Linked Chitosan Beads
  Abstract

Adsorption of dye from dyeing wastewater had been investigated using cross-linked chitosan beads as an adsorbent. The chitosan adsorbent was characterized by SEM, FT-IR and porosity [P]. Various parameters such as concentration of adsorbent (0.5 g/200mL to 2.5 g/200mL), pH (3-11), initial concentration of dye (50-250mg/L) and temperature (15-45 ) of adsorbate were studied. Langmuir and Freundlich isotherms were used to analyze the equilibrium data at different temperatures. Freundlich isotherm showed better correlation coefficient than the other models at all temperatures studied. The cross-linked chitosan adsorbent exhibits a high adsorption capacity to remove dye. And the adsorbent still has good adsorption capability after being reclaimed for 6 times. This study indicates that cross-linked chitosan is a promising adsorbent for removing dye from dyeing wastewater.
