title: [Impact on membrane separation process of volatile oil-bearing water body of notopterygii rhizoma et radix by inorganic salting pretreatment].
abstract: OBJECTIVE
  To explore the best pretreatment condition of inorganic salting on volatile oil-bearing water body of Notopterygii Rhizoma et Radix before membrane separation.
  
  
  METHODS
  The simulative system of volatile oil-bearing water body of Notopterygii Rhizoma et Radix was pre-treated before membrane separation 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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  Adding NaCl to volatile oil-bearing water body of Notopterygii Rhizoma et Radix before membrane separation can optimize membrane processes by improving membrane flux.
