摘　　要：An affinity-transport system, containing porous ceramic membranes bound with bovine serum albumin （BSA） was used for chiral separation of racemic tryptophan. The preparation of BSA modified ceramic membrane included three steps. Firstly, the membrane was modified with amino group using silanization with an amino silane. Secondly, the amino group modified membrane was bound with aldehyde group using gluteraldehyde. Finally, BSA was covalently bound on the surface of the ceramic membrane. Efficient separation of racemic tryptophan was carded out by performing permeation cell experiments, with BSA modified, porous ceramic membranes.An affinity-transport system, containing porous ceramic membranes bound with bovine serum albumin （BSA） was used for chiral separation of racemic tryptophan.
