摘　　要：目的:探索羌活含油水体在膜分离前加入无机盐预处理的最佳条件。方法:对羌活含油水体模拟体系进行膜前预处理,以无机盐的种类、加入量为考察因素,比较各膜通量及截油率,确定最佳加盐条件。结果:羌活含油水体在膜分离前加入无机盐的最佳条件为:按含油水体量2%的比例加入氯化钠固体;气相指纹图谱显示加入无机盐未影响挥发油的有效成分。结论:在羌活含油水体进行膜分离前加入氯化钠,能优化膜过程,提高膜通量。Objective ： To explore the best pretreatment condition of inorganic salting on volatile bil-bearing water body of Notopterygii Rhizoma et Radix before membrane separation. Method： The simulative system of volatile oil-bearing water body of Notopterygii Rhizoma et Radix was pre-treated before membrane sep^ation by salting. The best conditions of salting were determined by selecting types and amounts of inorganic salt as investigate factors and comparing membrane flux and oil retention rate. Result： The best pretreatment condition of inorganic salting on volatile oil-bearing water body of Notopterygii Rhizoma et Radix before membrane separation was to add 2% sodium chloride （NaCl） according to the amount of oil-bearing water body. Gas chromatographic fingerprint showed that inorganic salting did not affect the active ingredient of volatile oil. Conclusion ： Adding NaCl to volatile oil-bearing water body of Notopterygii Rhizoma et Radix before membrane separation can optimize membrane processes by improving membrane flux.
