| Abstract: | The oxalic acid is prepared by the nitric acid reacts with starch hydrolysate.The glucose is detected by polarization photometer,a conclusion was acquired that the content of glucose in the mother liquor is linear with optical rotation of the mother liquor,and the equation was regulated.The oxalic acid in the mother liquor is detected with high efficiency liquid chromatography.The rest acidic components was titrated with alkaline solution. |
