| Abstract: | The pure chitosan film and chitosan/activated carbon fiber composite membrane(w/w=1 ∶ 1.1) were prepared by cross-linking reaction.The effect of time,pH,temperature,initial oncentration of methyl orange solution and adsorbent dosage on the absorption of methyl orange were discussed.The results show that the optimized condition is the adsorption time 120 min;pH 6.0;temperature 10 ℃;initial concentration of methyl orange at 10 mg/L;and the remove rate of the methyl orange reach 99.54%. |
