| Summary: | Mixtures of sugars can be obtained from many sources. It primarily comprises glucose and xylose. Xylose is highly demand in industry and expensive sugar. It can used to produce xylitol and bioethanol. However, in the presence of the glucose, xylose cannot be converted into bioethanol efficiently. Since the structures of glucose and xylose have small differences, thus, the separation of these monosaccharides is necessary. The aimed of this research is to separate the glucose and xylose by using five different resins through the adsorption process. The resins included resins which include Amberlite IR 120, Lewatit Monoplus SP 112, Diaion PK 228, Lewatit Monoplus TP 214, and Lewatit CNP 105. In this project, the static method was performed. The glucose-xylose mixture was shaken in the incubator shaker at 160 rpm for 12 hours. In this research, different parameters were conducted, including 20 to 60 °C reaction temperature and different initial concentration of glucose and xylose. The efficiency of the resins was examined. The supernatant was collected and determined by using Anthrone Reaction method. Based on the results, all the resins that used were not suitable to separate the glucose and xylose. Moreover, it was found that an increase in the initial concentration and reaction temperature lead to an increase in the adsorption capacity. Desorption was recommended to be consider in the research. |
