Epichlorohydrin cross-linked chitosan (EP-Cs) was prepared was
characterized using Fourier transform infrared spectroscopy (FT-IR), X-ray
powder diffraction (XRD), thermal gravimetry (TG-DTA) and differential
calorimetric analysis (DSC), and used as adsorbent for methyl green (MG)
removal. Epy-Chit was soaked in methyl green solution with concentration of
40 mg/L using a batch adsorption system, to measure the adsorption capacity
of the EP-Cs and the percentage of MG removed from the aqueous solution.
The optimum MG adsorption on EP-Cs occurred at pH 7.8, agitation time of 60
minute and adsorbent dosage of 0.02 g were observed. Adsorption results
show that the EP-Cs exhibited the excellent performance for the MG removal
from aqueous solution. This study suggests that EP-Cs could be explored as an
adsorbent for removing other organic pollutants.
