The invention discloses a method for extracting adipic acid from fermentation broth and belongs to the field of bioengineering. The method is characterized in that the fermentation broth is subjected to solid-liquid separation, ultrafiltration, concentration, ion exchange, solution extraction, evaporation, crystallization and the like to obtain an end product (adipic acid). The yield and the purity of adipic acid extracted by the method reach high levels, the final yield can be up to 71.7%, and the purity can reach 95.86%.
