本文研究了纳滤法从大豆异黄酮水溶液中回收溶剂的可行性。使用了五种商用聚合物纳滤膜，STARMEM™122显示出可接受的通量和高截留率。采用响应曲面法(RSM)的中心复合设计(CCD)模拟温度、压力和料液浓度对大豆异黄酮膜通量和大豆异黄酮总截留率的影响。结果表明，所建立的模型与实验结果吻合较好，可以用来预测该纳滤过程。
Abstract In this paper, the feasibility of recovering the solvent from the aqueous ethanol solution of soybean isoflavones with nanofiltration (NF) was studied. Five commercially available polymeric NF membranes were employed and STARMEM™ 122 showed acceptable flux and high retention. The central composite design (CCD) of the response surface methodology (RSM) was applied to model the effects of temperature, pressure, and feed concentration on the permeate flux and the total soybean isoflavone retention. The results indicate that the developed models were in good agreement with the experimental results and they can be used to predict this NF process.
