Comparative study on adsorption of two cationic dyes by milled sugarcane bagasse
Zhang, Zhanying, O'Hara, Ian M., Kent, Geoff A., & Doherty, William O.S. (2013) Comparative study on adsorption of two cationic dyes by milled sugarcane bagasse. Industrial Crops and Products, 42, pp. 41-49.
Adsorptions of Rhodamine B (RhB) and Basic Blue 9 (BB9, also known as methylene blue) by sugarcane bagasse of different surface areas were compared in this study. There was a small gain in the amount of dye removed by increasing bagasse surface area from 0.57 m2/g to 1.81 m2/g. BB9 adsorption was less sensitive to surface area change than RhB adsorption. Adsorption capacity of 250 mg/L RhB on 1 g/L bagasse was 65.5 mg/g compared to a value of 30.7 mg/g obtained with BB9 under the same conditions. Increasing adsorption temperature (from 30 °C to 50 °C) while having no effect on RhB adsorption, slightly decreased BB9 adsorption by ~4%. The differences in adsorption performances between these dyes have been related to the molecular structure of the dyes and the surface chemistry of bagasse.
