The experiment on the type and dosage of extractants found that it is difficult for monovalent anionic salts (sodium chloride) to form a dual aqueous phase with PEG, and the dual aqueous phase formed by sodium sulfate is unstable. The demand for sodium carbonate is high, and the phosphate phase separation is slow. 2. The dual aqueous phase formed by ammonium sulfate is fast and stable. Therefore, ammonium sulfate was chosen as the salt for phase separation. Further experiments have found that the PEG2000 aqueous two-phase system is effective for VB. The extraction rate is not as high as PEG6000
