目的:探索中药含油水体模拟体系物化参数与超滤过程膜通量的相关性。方法:以草果等4味中药含油水体模拟体系为实验对象,在最佳膜工艺条件下进行油水分离,采集膜通量及原液、渗透液的物化参数,利用SPSS等计算机软件进行数据处理。结果:膜分离显著改变了含油水体的理化性质,导致电导率和浊度降低、pH升高;物化参数也显著影响膜过程,其通量随电导率、pH、浊度和黏度的不同而变化。结论:草果等4味中药含油水体模拟体系的物化参数与其超滤过程膜通量有着显著的相关性。

Study on correlation between physical and chemical parameters of oil-bearing water bodies and ultrafiltration membrane flux in four simulative system of traditional Chinese medicine volatile oil

Objective: To explore the correlation between physical and chemical parameters of oil-bearing water bodies and ultrafiltration flux in the four simulative system of traditional Chinese medicine(TCM)volatile oil. Method : Four simulative systems of TCM oil-bearing water bodies such as Tsao-ko Amomum Fruit were selected as the experimental subjects. The membrane separating under the best conditions was carried out, membrane flux, physical and chemical parameters of stock solution and permeate were collected, and SPSS computer software was used for data processing. Result : The membrane separation significantly changed the physical and chemical properties of oil-bearing water bodies, resulted in lower electrical conductivity and turbidity and pH value increased; Physical and chemical parameters also affected the membrane process significantly, and the flux varied with the electrical conductivity, pH, turbidity and viscosity. Conclusion : There is significant correlation between physical and chemical parameters of oil-bearing water bodies and their ultrafiltration flux in the four simulative systems of TCM volatile oil.
