| Abstract | This research is the first study on the development of chitosan membrane for dye adsorption from wastewater of a local reed mat industry. The results illustrated that synthesized chitosan membrane from 2%w/v chitosan flakes in 5%v/v acetic acid and formed in 0.1 M NaOH exhibited the best characteristics; the membrane was smooth, slightly elastic and possessed homogenously distributed pores. The maximum adsorption capacity was attained when the initial dye concentration was 3.0 g/l and the water flow rate of 1 l/min. Percentage of removal at such a condition was 43.89±1.72. The adsorption behavior could be fitted to the Fruendlich adsorption isotherm, indicating the heterogeneous adsorption. The adsorption capacity (Kf) was 2.87 mg/g, while the adsorption intensity (nf) was 1.1724. Percentage dye removal from real wastewater from the local reed industry was 32.31±0.98, which was significantly (p<0.05) lower than that obtained when tested with synthetic wastewater. That is because the real wastewater contained reed residues, which clogged the membrane, resulting therefore in the lower absorption capacity. |
