The present invention relates to a method for removing impurities in a xylose mother liquor. A xylose mother liquor produced during xylose production is used as a raw material, and the xylose mother liquor is pretreated by using a lytic polysaccharide monooxygenase (LPMO) and a copper ethylenediamine solution, so as to greatly reduce the viscosity of the xylose mother liquor; then, the xylose mother liquor is treated by a carbonation process to adjust the pH to acidic, thereby removing colloidal impurities to purify the xylose mother liquor, and thus, the xylose mother liquor can smoothly pass through a chromatographic separation device to obtain high-purity xylose. The present invention achieves the purpose of removing impurities in a xylose mother liquor by using a glycosyl hydrolase in combination with a carbonation process, thereby reducing the production costs and improving the utilization of the xylose mother liquor, and effectively removes colloidal impurities in the xylose mother ...
