Abstract: Disclosed is a method of separating carbohydrate, including: mixing formic acid with heteropoly acid, chloride or bromide of lithium, magnesium, calcium, zinc, or iron, or combinations thereof to form a mixing liquid. The method also includes dissolving a cellulose biomass by the mixing liquid to form a solution, mixing water and the solution to hydrolyze the cellulose biomass for forming a carbohydrate solution, and mixing an extractant and the carbohydrate solution to extract the formic acid out of the carbohydrate solution. The heteropoly acid, the chloride or bromide of lithium, magnesium, calcium, zinc, or iron, or combinations thereof in the carbohydrate solution is separated out of the carbohydrate solution by ion exclusion chromatography separation to obtain a carbohydrate.
