萃取剂的种类和用量实验发现,一价阴离子的盐(氯化钠)很难与PEG形成双水相,硫酸钠形成的双水相不稳定，碳酸钠的需要量较大,磷酸盐分相较慢2,硫酸铵形成的双水相快且稳定,因此选择硫酸铵作为分相的盐。进一步实验发现，PEG2000双水相体系对VB。的萃取率不如PEG6000.

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
