Abstract:
OBJECTIVETo separate essential oil of Caryophyllix flos from oil-in-water emulsion, and to enrich the essential oil by microfiltration (MF).
METHODUsing membrane flux and removal rate of COD as the indicatrixes, the membrane material as well as the operating conditions containing pressure, surface speed, temperature were optimized.
RESULTThe results showed that QWLM membrane of hydrophilic is the proper membrane, and the best operating conditions was at 0.06 MPa, 60 degrees C, and 150 r min(-1) stir speed.
CONCLUSIONIt can be concluded that MF is a reasonable way to enrich essential oil of C. flox.
